We are suddenly unable to add users to model driven app. We have setup uses in AAD including activating, assigning to security group, and assigning licenses. The security group has been associated to the environment. And user(s) assigned to the security group.

We also tried sharing the app, and sharing a canvass app--both getting errors (attached error2)
