The popup started showing up just recently, it's probably connected with unavaliability of To Do tasks with self-hosted Exchange.

The popup never disappears, which effectively prevents me to click anything underneath it. After clicking "Open To Do" link, it temporarely disappears, but on next application launch, it's back again.

Whenever i open teams it looks like this until i open the keyboard by tapping on the input box then go back it disappears

In android, online status of other colleagues getting displayed only once at the time of launching the app, later its not getting updated.
Sometimes in the MAC also facing similar issue.

Recently we have noticed that some users (primarily Androidusers) were able to share their screens in planned meetings, even though their role was set to attendee by default through meeting policies.

Incoming call answered on desktop. But mobile still shows as notification. Can only remove by rebooting phone

Our organization switched recently from Google chat and slack to Microsoft teams. When I get connected to teams meeting through Android mobile, I can face frequent disconnection. I never experienced this before over other 2 applications over mobile. Yes, I'm using mobile data for Android team meeting but I was doing the same for others apps too and it worked well.

I guess the Microsoft mobile app is heavy and needs more internet speed or something with applications. I'm just sharing my experience in the past 6 months.

While I wait for someone to reply, I switch to another app. I receive a push notification that a new message is available, switch back to the app (which is already in that chat), but I can't see the new message in the chat. I go "out" to the list of chats, back to the specific chat, and the message is there.
I exit

Call notifications stay active for hours if the call was never answered on smartphone but other device instead.
The only way to get rid of the notification is to force teams to stop in android settings.

When i try to use the app, it gets stuck in something that looks like a redirect loop.
I see the list of notifications for a split second before a spinner pops up.
Then i see the list again and it all repeats.
I can sneak in a tap on one of the menu items and see that it gets highlighted but it does not take me out of the loop.
I have closed the app and restarted it.
I have even done a forced stop through the android settings menu.

The app is completely unusable in this state.

Please see attached file. To remove the whitespace, I have to long press a message in the thread so that the reaction emojis pop up. I have to do that long press 2 or 3 times for the whitespace to disappear.

Teams app refreshes over and over, Can`t even click and keep a chat on screen.
Pixel 4a with Android 11 up to date, and Teams app latest version.

I had an incoming call during a meeting, which automatically put the meeting on hold when I picked it up.
After ending the call, I rejoined the call. From this moment, the mute/unmute button at the bottom was stuck at unmuted. I could only switch between muted/unmuted via the Android notification bar. But also when switching using the notification bar, the in-app button was stuck in showing "unmuted".

On a Samsung Note 9 with a USB type C (normal AKG Samsung ones) headset Teams is the only app that doesn't work with the headset for calls.

Teams seems to detect the headset, but when picking it as the audio device, the only audio comes out of the phone speaker like labels "device" in the audio selection menu and usb headset doesn't work.
