I'm a person who has a video conference with Zoom every day.
But there was a problem with the video a few days ago.
The camera in the device has been checked through another app to see if it is working, and access is also turned on in the camera settings.
But when I use video on Zoom, I don't see any alert pop-ups, I don't see myself, I only see a black screen. The camera lights up.
I've tried deleting and reinstalling zoom a few times, but it still doesn't work.
I'm really uncomfortable during the meeting, so I'm looking forward to your help.

I do a monthly Zoom where the focus is on a 99 year old class advisor "Les". He's mentally very sharp but not a techie and his vision is failing. There are often 40+ people on the Zoom. When someone speaks, Les has a hard time identifying who is talking as he scans the multiple screens to find the talker. As a result, he misses the beginning of the conversation.

What's the best way to have the current speaker's video prominently on-screen so Les doesn't have to look through multiple pages of participants? Ideally, Les' video would always be on-screen but its ok if that's not easy.

Thanks, 

In a Zoom meeting I hosted, towards the end of the meeting, several, but not all participants could no longer see my chat. This wasn't happening earlier in the session, so I don't know what changed. I had used the break-out room function several times during the session and some participants came and left and re-entered the meeting, but that is all in terms of disruptions. To resolve the problem, a participant who could see the chat copied and re-pasted it into the chat for everyone to see it. As host, this is far from ideal. It is the send time this has happened. I'd appreciate help resolving the issue.

hoping you can help me. 
I have a logitech brio 4k - using zoom with a green screen. Whenever I click I have a green screen with a virtual background the green screen remains visible and the image that is supposed to be projected onto the green screen is projected onto me? 

Cant figure it out at all...any ideas? Pic attached. 

Thanks in advance. 

I generally use my laptop with zoom. Have started to have problems with bluetooth headset(s), one is Sony WI-C400, the other is Sennheiser HD200. During the pre microphone/speaker test, I get the tones and microphone sensing. As soon as the actual acceptance from the host, everything is dead. Have toggled through the various headset options on the zoom window as well as W10 systems 'sound' page. 

This hasn't always been a problem, quite regularly had used the Sony unit. Problem has become apparent about 3 months ago. Have unpaired/repaired the units without success. The only thing I haven't done is uninstall/re-install zoom. Headsets work fine on Signal and WhatsApp.

I see some comments re possible conflict with android phone mic, but if not using the phone not sure why there could be a problem. Haven't tried turning phone bluetooth off.

Any suggestions?

I have been teaching yoga classes on my sunporch for three years. Until a month ago I used an iPad 7 and never had a problem with freezing. Speed tests say I have plenty of juice to teach the classes.

Now I am using my new IPad 10s and my classes are being ruined by freezing.

When I teach a class for the government even now, and click on the link they provide me, however, there is no freezing.

Could this problem relate to my Zoom account being weaker than the government's?

Why might the older IPad have worked well while the newer one doesn't?

What could be causing this problem and what might be the solutions?

Thanks for any help you can give,

Kathy
