I've been using Zoom for a year and a half now, and every time I enter a room or start a meeting I have to test my microphone. This is because almost every time I do, my mic output goes squeaky. Lucky for me I have both a remote mic and a system mic, but this is an unnecessary irritation that I hope has a software fix.  Can anyone help?

Hi. Everytime i enter a class with a host (a specific class) when he shares his screen my screen goes dark from time to time and then back to normal. I get at the beginning of the session a message "esmorecimento de imagem..." at the beginning of the session.

I'm recording the session with obs but that isn's a problem with other sessions of this user or in other computers/mobile. Only on this computer.

Can I set up an alternative host on the pro account and does the alternative host also have to have a pro account. Alternatively could I assign a co-host who could start the meeting if I am not there and would that person also need a paid account. I have looked at the help info but I’m still not sure.

Dear Community
I use different devices, computers, phone, wherever I am, for zoom.
How can I save these different devices,
to not have to go into the email address
every time in order to sign in with a code.
(I do not have activated by purpose the 2-factor-Authentification.)
thank you so much, B

My Zoom virtual background is not working. I have tried adding an app and I got an error message when it was pending to load the image. I do not have a green screen. Also, sometimes the virtual blur background will disappear randomly and I have month of laundry being examined by other students and professor in my Ph.d program, while I try to get my point across in class. Can you help? I have been trying to get it to work since the inception of opening my account and I tested almost all the variations of how to get it to work with a green screen, without, with the app, I have tried my own image, I have purchased a Zoom background and I have also tried the ones available, etc. Do you have any solutions? 

I created a meeting with my Basic account with a random meeting ID so that participants could join the meeting without my presence. What happens when all the participants leave? Will the meeting end, or will it continue until 40 min? I have concurrent meetings, and each meeting duration is 30 min. As I can't specify the time limit on recurring meetings in the basic plan, I wonder if the people joining the second meeting will see the dreaded message saying, "the host has another meeting in progress".
