Today, while co-hosting and speaking/presiding, a new issue came up. When I turned off screen sharing the second time, the window with images of participants had disappeared. I tried the usual ways to find it -- Alt-tab and minimizing the other windows, checking all the settings possible, but the view didn't come back until we went into breakout rooms. I looked for the setting on the chat window to re-attach it to the view window, and that setting was not there. So the people were just gone for a while.
Any ideas what new methods we need to do to find the participants if this happens?
