Hi I can't chat with my friend. I used to chat daily with her but today my problem began

When I send a contact request to her, she won't received my invitation, when she invites me, I accept and I see this following message

If i click on "Start Chat", I can't send a message because I see this warning

"Paula Moreno's account has been deleted by their account admin"

Hi, one big question. When i am sharing my STERO Sound from my PC to MAC the recipient receives the sound in MONO - its on his left side. When he is sharing his sound, I can listen to it in Stereo

The recipient is using a METRIK HALO ULN 2 Soundcard. Has anyone also this issue ? 

Thank you very much 

My "only authenticated users can join" function is permanently enabled. Any idea how to turn it off?

In my settings, it says it is off. But when in a zoom meeting it says its enabled. Any participant that wants to join a meeting has to authenticate before joining. I did not turn this function on and at some point it just started being permanently on regardless of what the "on / off" switch does in settings. Any ideas?

Previously, whenever I click on New Meeting my PMI would be used as the Meeting ID automatically.  That's because I was able to check the "Use My Personal Meeting ID (PMI)" box.  I now have a new paid account and that box is greyed out and is unavailable.  How can I go back to having my PMI used automatically?
