I have had Zoom for about 3 years and suddenly when i open it, it asks me if i want to connect to computer audio or phone audio, then when i connect to computer audio no one in the meeting can hear me and if they do start to hear me it is with an echo. Now, I have tried to open it on another computer thinking it was the computer that was the problem but on this computer it won't even let me start the session. Can someone help me please?

I was editing my recurring meetings this morning. I hit save from my phone. When I went on my laptop to send a reminder to all of the registrants, every meeting I've hosted has disappeared, both from PREVIOUS and SCHEDULED. 

I pay for my account yet I've discovered that Live Chat isn't an option. 

I have a meeting this evening. Does anyone have a solution?
Otherwise, I have to begin again and schedule new meetings.

Is there any way, as a guest / participant of a pre-scheduled meeting, to add the meeting and its link that I already have received to my PC Zoom app without connecting my calendar? If not, there really should be. There is no good reason not to allow us to paste the existing link into the app and have it generate a reminder.

I have a Logiteck 4k webcam for my presentations on Zoom, I need to share my screen, and I want my interlocutors to see the TV screen behind me, except that on Zoom, everything behind me is blurry due to auto focus.

I specify that the “blur my background” option is deactivated and I also specify that on the Logitech software when I do the test, there is no blur like on Zoom.

How can I permanently remove this blur behind me please?
