Hmm, that sounds strange. I had problems like that. The easier way to complete it was a simple restart of the zoom or even of the PC. Restarting an old computer could take some time if you get what I say. Recently I got promoted to another company that didn’t want to work on zoom because their old experience wasn’t that pleasant. After a while, they somehow hired brightvisionevents.co.uk for further work in groups. It was a time ago, and I still can’t forget working for that company.
