Once your tenant is using UPS (unified presence service), you should no longer have issues where DND changes back to available.
If you are on UPS, and are experiencing this issue, it would be super helpful if you can capture logs by typing Ctrl + Shift + Alt + 1, and send the file from your downloads folder along with any details to firstname.lastname@example.org.
Still happens for me on Mac. "You have Microsoft Teams Version 1.1.00.11551. It was last updated on 5/7/18."
Ideally this should be a platform feature (it is on iOS and Mac), but I understand that I may want different DND schedules for Teams vs. other things. Having the schedule work for all Teams platforms without having to reconfigure it would be highly useful.
Not only for iOS, but for Desktop Teams as well. Sometimes I want to work for a time period without being disturbed, but then would want Teams to turn off DND after that. Slack has "Snooze notifications for ... N minutes, M hours, etc." That seems like a useful model to follow.
Team's notifications are horrendous. At least let me turn them off when on DND (after making DND actually stay on), and better, stop notifying me after the first few, or let me control them in a finer-grained fashion (basic things like "only notify me for new chats or @-mentions", or "stop notifying me after X messages for Y minutes").
The ability to turn off emojis is still being worked upon.
Also, there is work to create a compact mode which will also help reduce white space… which in turn will impact some of the complaints are far as wasted space from the emojis as well, that have been voiced in the comments.
Stay tuned for more details.
Huge emojii and animations (whether animated emojii, animated images, memes, whatever) are a user interface issue; every user should have the opportunity to turn them off if they don't want them.
If we can't turn them off, we might as well just add the <BLINK> tag back into HTML. Seriously...
