Like so many others, I'm now locked out on my phone because the latest version is not compatible and they won't let me use it unless I update. I'm not willing to buy a new phone for this so I will just be getting along without it. ETA: I reached out to support and got a reply basically saying they have no intention of fixing this issue. They say it's to allow for innovation and keep customer data safe and secure.

If I could give it no stars I would! I have had this app on my phone since the start of 2019, I have never had an issue accessing my work channels, DM's etc. until recently. It logs in but nothing loads, I can't keep up with anything when I need to, the phone app is useless. When you have this as work communication when you work remotely you need it to work on your mobile devices, it currently doesn't. Please fix it!

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.
