Managing sound and video settings during Teams meetings and calls for optimal communication
I have the same problem also - video preview displays fine before joining a call, then as soon as i'm in the call all participants show black instead of the video display.
The only caveat to this is minimising teams during the call alows the current speaker to be seen in the minimised view.
Screenshare also diesnot display.
Really frustrating - please fix, its clearly a bug with Teams Work & School, as personal used to work perfectly fine.
