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.

Be it a Big Team or a Small group communication, Slack is quick and cleanly organized Extended feature set is nice, such as reminders. Search has gotten pretty good and notifications have been mostly reliable, though there are still occasional hiccups when you are both in the app and have a browser tab open. But its a commandable app which is helpful

This app is made by undecided people that cannot stick to one design. they keep changing the user experience every 5 minutes and I have to re-learn how to do simple things. Sending files in slack messes up the text encoding, and when I submit the issue with the troubled extensions, they basically ask me to do their job in sending files that have caused the issue and explain where the issue was, instead of testing themselves. Very amateur organisation. If I could, I wouldn't use it anymore.

Bug fixes
• Sometimes, occasionally, intermittently, a banner popped up in huddles saying AI was taking notes, even when AI notes were disabled for the workspace. We hope the fix contained in this update strikes the right note.
