Hi Jeannie,
Did you set the UNC Authentication to “UNC SSO for pre-assigned breakout rooms” rather than just the “UNC-CH?”
I’m happy to zoom with you to go over your settings. It has definitely been a challenge! We can also review the Meeting report for the participants and see how students were logging in.
We are having moderate-to-good success with Mike Crimmins’ >200 class.
