Latest update · v8.12.0

What the developer says changed (the verdict above weighs this against what reviewers report):

Bug fixes and performance improvements

Recurring themes

Notifications negative
Many users report persistent issues with notification badges showing incorrect counts, phantom notifications, or not clearing even after messages are read on the same or other devices. This makes the notification system unreliable and frustrating. The developer notes mention 'bug fixes', but this specific issue is still widely reported.R5R11R18R22
App Stability & Performance negative
Users frequently experience app crashes, freezing, black screens on launch, and general lag. These issues hinder productivity and make the app unreliable for critical communications. Despite 'performance improvements' in the release notes, users still report these problems.R3R8R9R23
Login & Authentication negative
A significant number of reviews highlight severe problems with logging in and authenticating, often leading to endless loops with the Authenticator app or being unable to access accounts. This is a critical barrier for users trying to use the app.R7R14R16R51
User Interface & Features negative
Some users feel the app's UI is getting worse with each update, becoming less customizable and more cluttered. There are also complaints about missing or buggy features, such as Airplay, screen sharing, poll creation, and issues with CarPlay or picture scrolling.R1R2R10R19
Cross-Device Syncing negative
Users report that messages read on one device (e.g., desktop) do not always clear notifications on the mobile app, and there are general syncing issues between different devices, leading to redundant notifications or missed messages.R5R11R122R254

Who it's for

This app is for individuals and teams who are required to use Microsoft Teams for work or school collaboration, particularly for chat, calls, and meetings R12R24R25. It is less suitable for users seeking a highly stable, bug-free experience, or those who rely heavily on accurate notifications and seamless cross-device syncing R5R18R22.

Evidence note: The recent review sample skews heavily negative, with a significant number of reviews citing similar critical bugs, especially regarding notifications and app stability. While some positive reviews exist, they often praise the core functionality without addressing the widespread issues reported by others. The developer's release notes for 'bug fixes and performance improvements' are directly contradicted by many recent user experiences.

  1. [R12] 5/5 · US Love it: This is one of my best apps to use when in a team meeting
  2. [R24] 5/5 · US Team: It’s easy to communicate with team
  3. [R25] 5/5 · US Dispatcher: Communication is key in this line of business. Good to know there’s a seamless application to keep us on point.
  4. [R49] 5/5 · US Better than anything: I’ve used them for a while now and I like how everything is setup. The chat, calls, video.
  5. [R95] 5/5 · US Works great!: I’ve used teams for years now but I have only bothered to try the app on my device for the past 8-10 months. Works great! No issues. Very convenient to be able to take teams with me this way. Thanks!
  6. [R140] 5/5 · US Mobile Computer: Easier than having to turn on your computer to see a message.
  7. [R202] 5/5 · US Transfer the call between systems is my favorite option: Transferring the call between laptop and mobile is my favorite option
  8. [R241] 5/5 · US Helpful: Keeps me connected when I’m on the go.
  9. [R145] 5/5 · US Teams Rules: Microsoft Teams sets the standard and sets it high for the most integrative and functional collaboration software, in my opinion. When combined within the greater Microsoft 365 platform experience, especially now with CoPilot, I never cease to be amazed and impressed. And Microsoft is always improving everything. Can’t beat it!
  10. [R153] 5/5 · US Easy and functional: Teams was easy to use chat, channels, meetings. The recordings are great to catch up when I miss the meetings due to conflicts. I like the copilot integration where all the meeting summaries, action items were presented. It’s great communication tool from MS.
  11. [R5] 2/5 · US Notifications/badges are still not working correctly: Notifications/badges are still not working correctly. If I’ve read a message on my MacBook or PC it’s still not updating the app badges as expected. This broke 3-4 updates ago! Please fix. It’s annoying and misleading.
  12. [R18] 1/5 · US Notifications: Recent updates to the phone not clearing notifications once you have seen them. Extremely frustrating now as it shows I have notifications that I thought I missed when that is not the case.
  13. [R22] 1/5 · US They can’t get it right!: There have been multiple updates in the last few weeks and my app still isn’t working properly. Every time I get a notification the app shows I have 10 notifications. Fix this please!!
  14. [R38] 1/5 · US Badge count is wrong: It's been month- every body reporting the same issue. Still they are not fixing. It's always showing some count.
  15. [R3] 1/5 · US Doesn’t open: When I open the app it shows a black screen with a white border at the bottom. Unusable
  16. [R8] 1/5 · US Crash: For several months now, Teams crashes while in a meeting. I keep missing important information or maybe in the middle of speaking.
  17. [R26] 1/5 · US Teams stuck at launch: Teams stuck at launch with a black screen. Reinstall and restart did not work. Other Microsoft apps are working fine.
  18. [R32] 1/5 · US App not working after ios 26.5 upgrade: After I upgraded my iPhone to iOS 26.5, have been facing a LOT of issues with teams app. When I open this app, it shows logo for close to 20 seconds and then crash. There is no surity if this app will work when I need it most to send a message to my team members. I deleted this app, restarted my phone and then have been trying to download it again from app s
  19. [R7] 1/5 · US Worst app: Worst app ever nothing works. Unable to create new account or even login I was logged out and the since it been a shame. This is very low quality. Wrong app, WORST !!!!
  20. [R14] 1/5 · US Authentication is atrocious: If you use this on mobile they make it impossible to authenticate on a single device, the app tries to authenticate on the authentication app via the authentication app. If you have a meeting to get to on mobile and you get signed out good luck. Also the outlook sign in solution also failed. This process all around is a failure.
  21. [R16] 1/5 · US Richest poor software in the world: The application functions just like any other email application with the added side effect that you will randomly not be able to sign in due to their Authenticator app being complete and total garbage. It will trap you in an endless loop of needing to use the Authenticator app to authenticate that you’re using the Authenticator app so you can authenticate teams.
  22. [R51] 1/5 · US Useless: They are useless as their hands are tied when you are locked out of your account. Might as well start over with gmail or any other email account that has a better system in place to authenticate you. I created a secondary account within my main account for my business and everything was fine. It never asked for a password so I figured the account used the same password as my main accoun
  23. [R9] 4/5 · US Great app but…: Great app, however I se notifications on the phone on a message, then when I open the app, I don’t see the message for a few minutes. That delay is annoying but livable .
  24. [R23] 2/5 · US Almost unusable without Wi-Fi: This app is a constant headache. If you’re not connected to Wi-Fi, it’s barely functional. Even if you’re on 5G with strong signal, it constantly displays. The spinning loading symbol. Has to be restarted, frequently, freezes up often. And that’s just for messaging! Meetings are even worse. As frustrating and error prone as the desktop teams app is, this is even wors
  25. [R31] 1/5 · US Overheating of the phone when I use the upgraded Teams app: Overheating of the phone when I use the upgraded Teams app. It’s causing too heat that I can feel my fingers almost hurting with the heat. This is unacceptable!! Pls get back the earlier version!
  26. [R55] 2/5 · US Killing my battery with his latest bill: I don’t know what you guys have done, but man you’re just sucking my battery dry with this bill the number one battery drainer on my phone according to the battery utile
  27. [R2] 3/5 · US No Airplay or Multicast functionality: I like Teams for its simplicity, and is adequate for the purpose for which I use it. However, the app itself lacks the functionality connect to my TV using Airplay or Multicast. Consequently, I have to haul around my heavy laptop to either cast to a smart TV or connect via HDMI.
  28. [R19] 5/5 · US Good initial support: Please continue adding capabilities, like screen sharing! Also, be able to not lock the app during a session as Vision Pro can detect when it’s taken off.
  29. [R30] 1/5 · US Won’t read messages on carplay: I have to ask Siri if any new notifications and then it reads the last one only. So it’s pointless if I’m traveling for work and I get a few messages. So yes it works fine on phone but definitely not with CarPlay
  30. [R34] 1/5 · US Can’t pin: I can no longer pin conversations or groups in the chat. Such an inconvenience
  31. [R1] 1/5 · US Somehow constantly getting worse: Somehow the teams app developers manage to make this more annoying and more difficult to use, with more wasted space and less usefulness with every single release. Teams is now the least customizable it's ever been, with more useless buttons and wasted screen space than ever before. It doesn't even feel like a chat app anymore. It feels like a poor attempt at a da
  32. [R244] 3/5 · US Laggy: If I use Teams across multiple devices during the week, it is constantly crashing or very delayed in receiving messages. If I stay on one device, it usually receives all the messages but takes forever to load. I don’t like how they keep changing the user interface and putting the buttons in different places, it makes it difficult to navigate the constant changes. Every time I update teams i
  33. [R11] 2/5 · US Notifies me all the time when I’m active on desktop: Even though I have it configured not to. Maddening.
  34. [R122] 4/5 · US Notification Badge issue and not syncing to other devices: Teams appears to have an issue with displaying the actual number of unread chats and is showing multiples when there is only one. In addition, Teams doesn’t appear to be syncing with other devices and adjusting the number of unread chats when they are read on another devise.
  35. [R254] 3/5 · GB Fails to sync at some times: Usually, I find Microsoft Teams to be generally a convenient app to use, but sometimes there are sync issues. The most recent issue I had came when a message came through on the Android version of Teams but not this iPadOS version. I had tried to repeatedly re-open the app to try and get it to sync with my other devices, but to no avail. I ultimately had to go to a las
  36. [R4] 1/5 · US What the hell, my personal account isn't working again: Is it dying? Personal users are again showing no organization invitation. I used it for so long before, and now suddenly it's not working. · translated
  37. [R13] 4/5 · US Teams: Good, but my kids can not call their friends
  38. [R27] 1/5 · US No More FaceTime: Recently teams has taken over as the default video call method on my phone making it so I can’t make a FaceTime call from the iMessage app
  39. [R36] 1/5 · US This apps hijacks your phone: Every time I FaceTime someone it opens up teams when I never changed any of the settings!
  40. [R10] 1/5 · US Copilot is useless: Copilot is a completely useless function and ruined teams
  41. [R294] 3/5 · GB I miss Skype 🥲: It’s not the same using Teams for video calls with family. It feels like I’m about to make a work call each time. And the chat box isn’t as user friendly.
