Hi,
I have been using thegetTeamsUserActivityUserDetail endpoint for months with no issue.
About one week ago the 'User Principal Name' column change from a real name to a whole bunch of weird characters (see below screenshot).

I can't relate the API payload to actual users now.
Is this a bug atm that's being fixed? It's been a week and I haven't heard anything on Google that would suggest it was a planned change.
If Microsoft is working on it then all is good. I'd just like to know
