I am an internal member of Microsoft and was notified the other day that my account had been migrated to Premium.
However, since this time the ANalyze in Excel feature ends up in an Azure authentication loop and crashed excel.
This is true for a number of people in the Asia PAcific organisation. Who should we turn to to get this fixed as this feature is extrememly importat to us.
There is an existing issue which has already been report internally to Power BI Team: CRI 48389469
You can also try to contact with the MSIT support to see if there is a workaround.
