I have no problems logging to login.microsoft.com using my personal account. However if I attempt to login to admin.microsoft.com while logged into login.microsoft.com I will not accept my username and password and ultimately get to "only your admin can reset your password". I've discovered that I can login to portal.azure.com but my account says "Restricted Tenant" and I am unable to see or view any details. It also is advising me to login with a different account. This restricted tenant problems seems related to my inability to login to admin.microsoft.com. Anyone have any thoughts on either?
