Oculus Go login? problem!

I want to use multiple devices Oculus Go.
My account can only login one time on one device.
My students have an e-mail which doesn’t work in oculus.
It’s an google address which doesnt end with @gmail.com
How can I solve this problem?
Also my office 365 account doesnt work in oculus. Had to make a gmail account to login proper.

When we have a pro trail account is it possible to upload to gallery? At this moment it doesnt work.
Or do we need an paid pro account?
