Hello I have question about zoom pro account

Q1:
We have 1 zoom pro account(It is Administrator) .
we Reset Zoom 2FA,IT's "OFF" but Setting does not work.
because still require 2FA coad when zoom login.
How Can I Rest ?

Q2:
We have 1 zoom pro account(It is Administrator) .
Can We Moving from another free Zoom Account to a licensed Account?
also
When Meeting-login by new licensed Account
Which Zoom delivery of the 2FA coad Is that new licensed Account or first acount(Administrator)?

i have turned off screen sharing, and when i try as the host and as the participant i cannot share.  However one participant has been able to share.  Any idea how? 

Also I can't seem to get back to being able to share as the host.  When i log in i have the option to share.  As soon as other participants join i no longer have ability to share.  Please help!!!

Curious if there is a way to share one's screen, but have it display as another attendee instead of occupying the entire screen and minimizing attendee displays. 

In context: I have a question set to explore with a group of attendees. I'd like to have the question display itself as "an attendee," so it's minimized and utilized as a quick reference instead of the main focus. I want to keep the focus on the people.

Thanks for the assist!

I am furious! I am an TEFL teacher earning very little and have used zoom for the last 2 years with one to one lessons of one hour.  My students and I are now very used to zoom, but there is no way I can afford to upgrade and pay 120 pounds!  What's more, I had NO warning of this!
