Classroom App lost all classes on Teacher iPad

[ed_uden]

One of our Teachers has lost all classes in their Classroom app on their 2020 iPad running iOS15.

Error message:  Configuration invalid.  Classroom must be configured with a valid education onfiguration profile.  Contact you network administrator for assistance.

I was working with iOS15 for a number of days, until late this afternoon, and the classes have all just disappeared on this one Teacher ipad.  Other teachers are ok.

We're currently experiencing this issue, and it's expanding at an alarming rate. My current estimation is that the issue occurs the first time Jamf pushes out a new EDU profile to the device after it was upgraded to iOS 15. It doesn't seem to affect devices that clean installed iOS 15.

We are seeing the same error as well. Has there been a solution other than reinstalling the iOS?

Do you think these issues are related to PI-010141? We had a similar issue, not related to iOS 15 but to our upgrade of the Java version on our host server - we are self-hosted.
