I've created a new user in my organization.  The user has a full license to both Zoom chat and Phone.

When I go into Zoom chat, the user does not display in Contacts and does not show up when I start typing their Name/email for a new Chat message.  

Image showing beginning type of the name, Ryan; only shows another user Ryan B.  Also attached, image showing that the user is Ryan A.

Why is my organizational user not showing up?

If I use the user's email address, Zoom tags as an External user (which causes other issues based on our backend rules).

I have used the free basic zoom for a while, but for work reasons had to upgrade to zoom pro. Problem is, even though I've paid for it & have the receipt, I can't seem to get it to change from basic to pro. What am I doing wrong? I've tried to phone zoom, but no-one ever actually talks to me. I just get a recording & a lot of canned music. Please, if someone can help, I'd be very grateful!

During Zoom meetings, I am getting a pop-up message on my screen saying that I am being signed out because someone has signed in from a different device.  I've been using Zoom for several months, and this just started happening. What does it mean, and what should I do?

I have dual monitors and have my powerpoint in display mode on my second monitor.  When I'm presenting in Zoom, I have to have my chat visible to see participants responses and it needs to be on the same screen as the presentation on my main monitor.  I have to constantly move the chat box around to view the presentation.  Is there a way to lock in the chat to the side of the presentation instead of moving it around constantly?  

Thanks
