We like to go out of practice mode 15 minutes prior to start so attendees can start to get in and see some informational slides. Since the broadcast has not started they still cannot hear/see panelists. However, now it looks like they can see the "paused" webcam screens for anyone who is sharing their webcam. Is there a way to keep those hidden without having everyone turn off webcams until the broadcast begins. We would still like to chat pre-event and see faces, but do not want attendees to see some of the names.
