A user reports have no camera function during zoom meeting.  He uses Zoom VDI client on a remote desktop server host.  I have contacted zoom support and was advised to update the VDI plugin (for Azure Virtual Desktop and Windows 365 Cloud PC) on his thin client to the latest (5.16.0).  I am uninstalled, rebooted and reinstall both the plug-ins and the client VDI client but still did not see the camera being recognized.  I logged on the client, navigated to statistics >  VDI and found that the plugin was in "connecting" state and the statistic disappeared in seconds.  I checked my VDI client (also 5.16.0) on my desktop.  The VDI plug-in status is in connected and it recognized my webcam which is the same brand as what the user has and video works.  I have even tried a lower version of the VDI plugins (5.15.2) but zoom still does not recognize the webcam.  I also made sure the defender firewall was set to "allow" on zoom meeting and zoom conference.  I am not sure what else to try and how to get some sort of logs from zoom.  Please help.  thanks

Сегодня неожиданно пропала функция "демонстрация экрана". Т.е. она есть, но экран не демонстрируется другим. При проверке выяснилось, что из трёх участников зума я один не вижу экран, который другой участник демонстрирует. Т.е. ни меня не видят, ни я не вижу. Что это может быть?

Today the “screen sharing” function suddenly disappeared. Those. it is there, but the screen is not shown to others. When checking, it turned out that out of three conference participants, I am the only one who cannot see the screen that the other participant is showing. Those. neither they see me nor I see. What could it be?

While screen sharing with my student, his screen will go from full to small. He does not know what he clicks on, or it may be doing it on its own. I do not know how to help him or his mom. We have been ending the meeting and re-joining to go back to full screen. How can I help them 

Hi, I have been using this Zoom Id for education purpose since the start of the pandemic. Recently i.e. January 2022, I am facing a lot of issues connecting the meeting as a host and cannot see more than 1 or 2 participants video. My internet speed is excellent. I think there is some setting or technical issue as I do not face any problem using a second account  which is also a free account that I use for the same purpose (education).

Kindly help and suggest what I need to do.

Thank you
