If I change the layout to rolling, the screen will be black for about 30 seconds and I won't see the screen of the participant. After about 30 seconds, the layout will be displayed normally. I'd like to know the cause of this problem.
A total of 15 people will participate in the meeting. When I do a meeting with the layout in default, I see the faces of all the attendees, but when I change to Rolling, some of the participants turn into black screens in a momentarily.
