Since a recent update, I can no longer see people in breakout rooms. Sound is ok and they can see me but my screen is black with a message that it may take a few minutes to join room stuck on the screen. Also there is no access to any controls. If the host closes the breakout room, I then have the same issue in the main room. On a Galaxy Tab A. Other people are posting on the Zoom Community page about the same issue. Please fix!
