I have a scheduled meeting that I need to join every week. However, no one can hear me when I speak. Before joining the scheduled call, I entered another meeting room/link where the microphone works perfectly. Additionally, when I entered the scheduled meeting, I would select the "test microphone and speaker" option beforehand. I can hear myself, and it works perfectly fine during the test. I have also performed the microphone test in the settings.

I don't believe my headphone microphone is the issue, as it works in other applications. I have tried different headphone microphones, and all of them have the same issue too.

Is it possible that the host has disabled my ability to speak in the meeting? Are there any solutions to resolve this issue?

When I go to send the invitation out to the participants, the 'send' button is not working.  It is greyed out.  I have to exit the calendar event in outlook and then it will ask me do I want to send the invitations to the participants.  This has only just started happening.  I have the latest version of zoom.

When I haven't used zoom for a while it wants to use an OTP (one time passcode) to allow me to sign in. The issue with this is, the passcode doesn't immediately arrive and can sometimes take an hour or even half a day to arrive. Consequently, by the time it arrives it is no longer valid so there have been times when I just simply can't access zoom at all! Ridiculous - and I don't seem to have the option to turn it off ....
