The zoom application ( on windows 10 ) have been reported that "your network bandwidth is low". I have checked with a speedtest apllication (110/90M ) and the network bandwith is more than enough. There were no clients on this network at that time. Please, try to investigate what can be the problem. I was connected to an AP12.
I had to switch back to my backup WIFI ( Mikrotik ) and after that everything was problem free.
Try change "Visibility Control" from "Application Details (default)" to "Application activity summary".
Application > Settings > Visibility and control
I don't have time to troubleshoot meanwhile I'm in a live video conference :-), and these devices can't provide any log messages to analyze what was was problem at a specific time range.
