Cannot unmute after putting on hold
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".
