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.

I use Slack on my desktop (browser) and the mobile app, and it's very frustrating that notifications aren't in sync anymore. My phone still shows notifications that I read hours ago in the browser. I know that this affects our entire team (not sure about iOS). Please fix this, this used to work in the past. I had mixed feelings about the new UI, but I'm actually fine with it now. (Though not sure if it's a good idea to have a non-standard navigation for the average user...)

Bug Fixes
• All bugs that were fixed in this release were too small for the eye to see or too fiddly for human words to describe. Nevertheless, work was done, things tinkered with and the app became subtly better.
