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

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.

Android app is quite buggy. All direct messages have 'Couldn't send, tap to try again' error with a white picture above it. This is for pictures send from desktop. While these have been transferred just fine. Very annoying since you have to constantly scroll up to see the last direct message text. Please fix this. This has been an issue for over 1 year.

What's new

Bug fixes
• Incoming huddles notifications were not appearing when devices were locked, which is a little like a doorbell only working when the front door is already open. Ding-dong. Who's there? It's a bug fix.
• When creating a new message, it wasn't possible to add multiple people to a DM (despite the checkboxes tantalizingly suggesting it was). We apologize for the mixed messages. Bug fixed? Check.
