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.

For an app that has been around so long, so much practical functionality is not present. I have yet to find a way to jump from a conversation, into a channel, and back to the conversation to find information. Why can't I swipe left/right to get access to multiple areas of information? or tabs at the top? If the keyboard is too tall, slack does not realize the chat box area to let me see what I am typing. I cannot scroll up/down until the chat box is full. This includes searching for users.
