  1. [R1] KakaoTalk 1/5 · US Can’t talk to my friends: I have verified my phone number multiple times and they just won't let me use the app. Maybe it's because I'm an American? I'm not sure but I can't log in or use my account to talk to my friends
  2. [R4] KakaoTalk 2/5 · US New update is terrible: Update deleted all chat rooms and temporary back up kept coming as an error. Then it says the account is expired and asks you to start over. When you choose to restore back up it doesn’t do anything. Terrible update. All my memories are lost. They don’t allow non Korean numbers to have a cloud for back up that’s so ridiculous when they are aware many foreigners use this app
  3. [R6] KakaoTalk 3/5 · US 👎🏽: It constantly requires verification. There's too much unnecessary stuff in the interface. Always a problem with logging in. · translated
  4. [R10] KakaoTalk 1/5 · US Can’t log in: It keeps trying to send an international message for authorization, and it miserably fails.
  5. [R3] KakaoTalk 3/5 · US STOP WITH RANDOM ADS: I wish there was an English option great app but WHY ARE THERE SO MANY ADS???? And why can’t I block them?!?!
  6. [R15] KakaoTalk 3/5 · US Please bring it back: Please, please, get rid of this Instagram-like feed. Please, please, please. · translated
  7. [R17] KakaoTalk 5/5 · US Used in any country: Living in the US, it's convenient for free calls, urgent matters, sending photos, and so on. But there are too many ads these days... · translated
  8. [R18] KakaoTalk 3/5 · US Now with ads: Oh lord… kakao with ads. I hate it. Leave us alone!
  9. [R7] KakaoTalk 2/5 · US I think the global kakaotalk kinda need to get improve: I try to join communities of my fav Kpop artists but it always show me the message that I need a Korean phone and I don’t have one, like what do you expect someone from outside Korea to get a phone number in Korea when they don’t even live there I hope kakao talk can improve this.
  10. [R27] KakaoTalk 3/5 · GB Can’t login: Hi, I can’t login to my detail. Can you help?
  11. [R43] KakaoTalk 2/5 · US Buggy app: Such a buggy app. I’ve been seeing an issue for months and months where a contact’s profile keeps showing the wrong name! And interestingly, the wrong name has been applied to multiple contacts. PLEASE fix this. Additionally I’ve never used a service where you couldn’t change your email address. What a joke!
  12. [R48] KakaoTalk 3/5 · GB It’s good but has its faults: I was logged out of my account for no reason only to find that when I tried to log back in my account had been disabled! I tried to resolve it in every way possible but I couldn’t and I can’t make a new account either because it’s registered with my phone number. The good parts of the app was the theme and custom design function for the chats among other things.
  13. [R54] KakaoTalk 3/5 · GB Bugs.: I love the app and speaking Korean with friends, however it keeps disabling my account and telling me I cannot join open chats or message others first due to security setting, even though everything I’ve said was in the guide lines. Please help so I don’t have to uninstall 🥺
  14. [R25] KakaoTalk 1/5 · US Really, hiding ads as DM?: I don’t know who approved it. But it’s crazy that they inject ads into your DMs but make it look like someone messaged you. Kakao already takes up 1/3 of the DM space for their banner ads. But this is a new level of invasive ads placements. Better to just delete the app and move to another platform.
  15. [R82] WhatsApp Messenger 1/5 · US Unfair Excessive suspensions: Account suspended excessively. My WhatsApp account has been suspended 3 times in the last 2 weeks for nothing. Fix this. I may delete my account because these unfair and unfounded suspensions make the App useless. They never explain the reason for the suspension.
  16. [R91] WhatsApp Messenger 1/5 · US Account review for no reason: You could fix this but you won’t acknowledge you have issues. Dev team just collecting a check.
  17. [R93] WhatsApp Messenger 3/5 · GB Banned for absolutely no reason: I’ve decided to swap numbers to my new phone and when i did i tried texting people and it failed so i was like okay ill wait 3 minutes pass and then im banned for what reason? Not even sure myself I haven’t broken any terms n Conditions
  18. [R99] WhatsApp Messenger 3/5 · GB Gg: Just random vans and suspensions with the stupid AI platform
