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.

You must have a phone no older than 3 years old or they lock you out. I have over 300 popular apps on my phone and this is the ONLY one that doesn't work. My phone is still very nice. I'm not going to update it for one app. It's inexcusable for an app as integral to business workflows as Slack to kill support for past Android versions so quickly.

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.
