  1. [R1] Microsoft Excel 2/5 · US Comes up Short on Key Excel Features: Key features missing that drive poor productivity - Would not recommend unless you are desperate and it’s free too. Simple key features are missing from the iOS version of Microsoft Excel… >> Poor graph features >> “Advanced File” option(s) missing >> User interfaces are weak compared to Windows Desk / Lap top versions >> Etc…Etc…Etc
  2. [R3] Microsoft Excel 3/5 · US Typical Microsoft: Does not support vba macros Does not support editing without paying Wow i can see my data but….. Sometimes the bottom and top toolbars disappears when you scroll down and you have to hit fx to get it back or scroll up. This is not always convenient. This is cumbersome and can lead to errors
  3. [R6] Microsoft Excel 3/5 · US App is missing a lot of functionality: App for Excel is missing many simple features that are in the desktop version.
  4. [R8] Microsoft Excel 5/5 · US Data Analysis: Love it,…easy to use yet powerful to manage data for day to day easy and fast tasks, suitable for all levels of experience and knowledge.
  5. [R14] Microsoft Excel 1/5 · US Grand Ave. spread sheet: Difficult to print
  6. [R4] Microsoft Excel 1/5 · US Constantly logged out: How many times can I get logged out of an account? Every time I go to use this I am required to log in again. It is almost impossible to use this program offline.
  7. [R7] Microsoft Excel 2/5 · US A Problem: Good app, but a major problem, why do I have to sing almost every time I want to edit a form?!!!! Sometimes I don’t have no internet connection so I can’t use my forms.
  8. [R10] Microsoft Excel 1/5 · US Microsoft's sign in system makes their products unusable: Literally have to sign in every time I try to open a document or join a teams call. It never remembers me and it never works to log n. It's so horrible. I literally have two separate paid 365 accounts and Microsoft cannot let me sign into either one. There's always some random error message that says something like "something went wrong". N
  9. [R24] Microsoft Excel 2/5 · US Recent files not saved: A file I’ve had for years all of a sudden is gone.
  10. [R18] Microsoft Excel 1/5 · US Paid App: Using it On my iPad isn’t for free
  11. [R26] Microsoft Excel 1/5 · US Inconsistent uses between iPad and iPhone: You need to be logged in and with a paid account on iPad to print. For iPhone, you just need to be logged in. Makes excel completely useless on iPad.
  12. [R38] Microsoft Excel 1/5 · US Bought and Paid for but can’t share easily: I have this version for my iPad and another for my Mac; the versions do not play well with each other and you need to pay another version to have them be able to share even when at home
  13. [R44] Microsoft Excel 1/5 · US Nothing ever works.: Half the time it won’t let me edit, even though we pay a subscription. Sometimes it doesn’t load. It’s a terrible program.
  14. [R56] Microsoft 365 Copilot 3/5 · US missing functionality: when you have moved from Microsoft Office suite to Microsoft Copilot, many of the applications are missing functionality that has been embedded for years
  15. [R78] Microsoft 365 Copilot 1/5 · US Trash: It doesn't make PDFs like it use to. Now its just a picture and not formatted like a real PDF. It basically took it out and made a new app Lens and wants to make you pay for another subscription when you've already paid for one before they changed this to copilot.
  16. [R100] Microsoft 365 Copilot 1/5 · US No Feature only copilot: In recent updates they have removed microsoft lens, and the ability to open and edit office files. The app is just copilot AI basically.
  17. [R51] Microsoft 365 Copilot 1/5 · US Confusing AF: I just reset my password couple days ago and it’s not recognizing it. Then it asked me to update it which I hate doing because I really have a process for my passwords. Then it won’t take me back to the email which I really. This is so confusing.
  18. [R54] Microsoft 365 Copilot 1/5 · US Not downloading: Cannot get it to sign me in with my personal account, even when deleting my work account. Cannot download a family slideshow for PowerPoint
  19. [R72] Microsoft 365 Copilot 1/5 · US Files won’t open: For the past month I am unable to open my files from the 365 copilot app
  20. [R74] Microsoft 365 Copilot 1/5 · US Embarrassingly Bad: The entire Copilot platform is so buggy that it is effectively not functional. I would say at least half of the responses that I receive are hallucinations or flat out lies. Of the half which or not, another half of that is excuses about the agent not being able to perform a simple task because the tool isn’t working properly or not knowing how to use it’s own features.
