It was an unpleasant and unexpected experience to have students unable to use their cameras once as I had over 30 persons on a call. When I as the host, disabled my own camera, I was then unable to reuse my camera for the remainder of the lesson. Two real issues:
1. this limitation is unacceptable (I can have 150 participants!) as the nature of my lessons is interactive with all users. I understand this may be fixed in a future update but when?
2. As a host, I should have been able to reattach and use my camera as this was quite disappointing to my students. The host camera should have a higher prioritization I would think.
