Hi all,
In the past I have been able to add a user to a security role for a given environment without them being in a security group (or without a security group assigned to the Environment).
In the last few days when I search for some users there are no results.
I have confirmed the users have the appropriate Power Apps license.
Odd thing is, one of the users exists in security roles in another environment. Their licensing has not changed.
I can still search for some other users. and I tried full email address, username, first name, last name.

Any ideas?
Thank you
