Have one portal
There are too many portals for administrators and end users. Users can be confused by the myapps.microsoft.com and portal.office.com/myapps pages. Each of these pages provides a different end user experiece. Administrative portals are a nightmare. Trying to provide temporary MFA code for a user involves going thorugh multiple portals to get to the appropriate area, and the user experience for this is still not clear.
Thanks for the feedback! We are in process of trying to align My Apps with the Office experience to help the experience be more fluid between users. Please share more feedback and ideas around this!
