• Share and edit documents and collaborate with the right people, all in Slack
• Integrate the tools and services you already use into your workflow, including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk and more
• Easily search a central knowledge base that automatically indexes and archives your team’s past conversations and files

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.

Team or group communication is quick and cleanly organized when you use slack. The extended feature set is nice, such as reminders, but mostly I use this for the basics. Search has gotten pretty good and notifications have been mostly reliable in recent years, though there are still occasional hiccups when you are both in the app and have a browser tab open, even if one is backgrounded. Best of all, the app is pretty low impact on battery life and system performance.

what on earth could you be doing that you won't support an older version of Android? given the choice of having to buy an entirely new phone or not having slack, a work app, on my phone, not having the app wins out. forcing obsolescence is not the way, but at least I'll be free of this all starting Sept 1 edit: and you can't even be bothered to actually read the negative reviews before auto posting asking users to contact you about the issue. no thanks

What's new

Bug fixes
• Case-conscious users noticed that two versions of the same email address could be present when adding a workspace. This duplicative deception would occur if you already had an account, then accepted an invite where that same email was written in all caps. This bug has been fixed. Hang on, let's try that again: THIS BUG HAS BEEN FIXED.
