Muting all attendands, then users can not unmute (at meet.jit.si)

a group of my school users reported today that when the teacher used the “mute all” function at meet.jit.si , and then asked some students to unmute, the microphone remained disabled, even if they closed the room and entered again. Most of them are using Chrome on Windows, but some use Chrome on Android.

Does anyone have experienced this problem? Any solution if so?

Thanks in advanced.

I’ve just discovered a similar issue here: Meet.jit.si: 24 Aug Testing Session: Unmute failures on iPad running iOS 13.6.1 using Safari
