Can two teachers use the same classroom? (co-hosting)

Yes, but how it is done depends on whether the teachers also share an internet connection (IP address).

If two teachers need teach a class at the same time (“co-hosting”):

Important! If TEACHER 1 and 2 sign in with the same account from the same internet connection, the first to sign in will be signed out automatically.

In this case, TEACHER 2 should join the class “as a student” using the “Zoom ID” on AIRS).
