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.

look this is a great app except this one thing and it's causing me so much frustration I'm taking two stars off. there needs to be an automatic draft saving feature. when I type out paragraph after paragraph, I don't appreciate it all being erased the moment I lock my phone or accidentally swipe from the edge to go back. right now my phone is in power saving mode but this should not make any difference, but I'm letting you know, just in case.

• Our URL auto-detector was a bit overzealous, adding link formatting back to text after you removed it. There's a line between autocorrect and auto-incorrect, and it looks like we found it.
