In my Zoom settings, I have 'Participant Video' enabled (i.e. 'Start meetings with participant video on. Participants can change this during the meeting.'). However, when a participant joins, they still have to manually start their video and unmute themselves. 

Am I doing something wrong?

After recording my zoom to my computer, I renamed the recorded meeting video file so I would be able to remember which one it was. Then I went to zoom to share the link and it said “unable to play because file was renamed” but I don’t know how to restore the original file name so zoom can retrieve it! 

It has been like this for about a month I logged into my schools zoom meeting. For about 30 minutes into the meeting I didn't have a problem came back to the meeting and my screen was very pixelated with the random colors and bright stripes that moved up and down the video. Ever since then every time I log in for my schools meeting it looks the same very colorful, choppy and the audio is horrible. I tried everything under the sun unfortunately my laptop is the main way I get on my zoom meeting and the laptop I have comes in S mode. So I've been using zoom through browser because my laptop will not allow me to download the actual zoom app.

Hello, I would like to ask,

whether it is possible to join a recurring Zoom meeting entirely by voice. It's about a blind person who can't operate the touchscreen on the iPad.

So it's not about joining a meeting that you have planned yourself, but participating as a listener in a regular event.
