We are in a process of Office 365 migration of our user accounts. User
jdoe@domain.com is also an email user, but has full rights to PowerBI, he creates PowerBI dashboards.
I changed his UPN from jdoe@domain.com to johndoe@domain.com but afterwards he was not able to manage his own PowerBI dashboards.
So I changed back his UPN to jdoe@domain.com, this restored parts of the PowerBI dashboard functionality, BUT user is now unable to change credentials of PowerBI gateways. Also the PowerBI gateways are greyed out and we cannot refresh data.
Any ideas how to fix this? It looks to me as a fault at the Azure AD side wich I cannot correct myself.
