I am trying to leverage App Insights to get authenticated users for my Power Apps portal. Was setting up things as described by Psyionic here: https://www.dancingwithcrm.com/powerappsportals-tracking-using-azure-app-insights/.
That approach was working fine until Oct 12th when suddenly user_AuthenticatedId was not populated anymore. Did of course not change anything in the snippet nor any app insights settings. Would be great if anyone could help getting back on track ... Thanks!!
