I hold weekly office hours in Zoom, ranging from 60 to 90 minutes. They are drop-in sessions. Today two students dropped in right at the start, talked with me for about 5 minutes, and then exited. There were 55 minutes left in the session. But because of this feature, the session automatically ended after 40 minutes and I wasn't able to re-start the session. The result is that if any students wanted to join me toward the end of the session, they can't.

This is a ridiculous feature. Please fix it.

I am a basic user, Version: 6.4.3 (52139), Mac Pro. I am trying to turn off the blue screen background, which I presume is a virtual background. I'm not even sure how I got one. Changing virtual background to None does nothing. Trying to follow instructions to change the background have gotten me nowhere. I tried following the instruction "As an admin (logged in), navigate to zoom.us/account/setting, then Meeting -> In Meeting (Advanced)You'll find the following options for your entire org's account, including 'Require user s to always use virtual background'. Disable this and unlock the virtual background setting if this is locked." I am not "authorized" although I am the sole owner of the account.  How can I become the admin of my own account?

After signing in, following other the other instructions I found doesn't work because my interface doesn't seem to match the instructions:

To enable or disable Virtual background for all users in the account:

1. Sign in to the Zoom web portal as an admin with permission to edit account settings.
2. In the navigation menu, click Account Management then Account Settings.  [NO ACCOUNT SETTINGS UNDER ACCOUNT MANAGEMENT ergo no meeting tab or In Meeting (Advanced) links. I have screen shots if necessary.]
3. Click the Meeting tab.
4. Under In Meeting (Advanced), click the Virtual background toggle to enable or disable it.
5. If a verification dialog appears, click Enable or Disable to verify the change.

I currently have a Pro license, and I'm running an upcoming event that will have both concurrent Meetings and concurrent Webinars. I know I need individual licenses for each one that runs concurrently, but I'm trying to figure out if I can simultaneously run a Meeting and a Webinar using the same account/email address, presuming I have the Webinar add-on.  I won't be presenting--just the behind-the-scenes administrator for all of the sessions.
