I just want a bug report (Work Item = Bug) on a very specific areapath. 

th. So far i haven't been able. Any help is welcome







To connect to Team Services, the first step requires you to authorize Power BI to access your Team Services account. Choose between one of these two connection scenarios when connecting to Power BI:

  • Scenario #1: You use the same Azure Active Directory (AAD) account to log in to Team Services and Power BI.

  • Scenario #2: You use an MSA (Microsoft account/LiveID) to log in to Team Services or you use different AAD credentials to log into Team Services than you use to log into Power BI.

Please refer to the link below to see the details.
