Major performance issues after update. App was easily 10/10 for years. Some update months ago and it has been unusable. I read thru all the complaints and responses in the reviews here - delete and redownlaod the app, clear the cache, wipe my phone and restart anew all of it. Im running a Galaxy S21 Ultra - specs should be fine. Chats fail to load in part or entirely Cannot find chat groups in the list Search cannot find chat groups Messages fail to send ... Heartbreaking

Yikes! We're very sorry about the frustrating experience. We'll get our experts to dig into this for you. Please tap your profile picture, then head to "Preferences". Under "Troubleshooting", tap "Send feedback and logs" to generate a report for us. Our Android team will reply via email as soon as possible.

I frequently see that there is an unread message, but everything is ready. also integrations periodically stop working. resetting the cache temporarily fixed the issues, but then they return and I shouldn't need to reset the cache in the first place. it seems like there's very low android support or not many people at slack actually using the app on Android.

I'm getting my messages delayed quite often...sometimes the previous messages don't show up, but the latest messages show up. After I close the application and reopen, I'll get the messages properly. Sometimes I do cache clear to fix - but it's annoying to do often. Also, when I check a new message, the notification won't clear indicating that it's read. I use Slack both on phone and laptop. At first I thought this might be due to network issues, but it's not the case.

Could you use the "Send report" option in the app's "Settings - Notification Settings - Troubleshoot notifications" page to flag this issue with us and let us know more about the trouble the app is running into? The option will be under the icon in the upper-right corner if the test doesn't show it.
