Latest update is really awful. Now messages often won't send or take several minutes to send, and I have either a blank Slack notification on my notification bar the whole time it tries to send a message, or there's one that says "Sending message..." that appears and disappears over several minutes. For each message sent. Edit: I cleared the apps cache like suggested and it didn't help. I also now have a permanent blank slack notification, even when the app isn't being used and is force closed.

Hello! We recommend resetting the app's cache when you run into behavior like this. You can do so from the app's "You" tab > "Preferences". If you continue to run into trouble after this, please head to the "You" tab > "Preferences" > "Send Feedback" to flag this with our support team and provide some logs needed to investigate. We'll be happy ...

The new ui puts every workspace at the same layer. Suddenly I have 7 channels all named "announcements," with no way to tell which one is which. This makes the app useless for my teams. We're already seeing usage dropping off dramatically. UPDATE: while you can isolate groups in both the desktop and mobile app, it doesn't make it easy to find and most of my students never find it. It also makes notifications bewildering. Most of the class gave up and moved off the system.

Horrible, it hat had issues closing DMs for years, and they never do anything to fix the problem. A newer issue is now. Occasionally, when I get new messages, I can see the count, but there is no new message available to view until hours later or if I log in a pc. Setting yourself away constantly reverts to available unless you wait almost a minute to exit out of the screen.
