SQL Server Reporting Services (Mobile Reports) Android - Drill Through not working

Hi @all, 

we have a problem with the Power BI App connecting to a Report Server and displaying a Mobile Report. Our customers and me cannot do a thrillthrough action to a sub-report. -> Error message translated from german: "Error Occured. Please try again later". The loading Screen lasts then forever (see attached Screenshot). 

On the Power BI App for iOS everything works correctly and you can navigate via Drill-Through to other Reports. 

Android Version: 9

Power BI App Version: 2.2.210708.2138974

SSRS Version: 13.0.5888.11 / Enterprise Edition -> Should be the latest cumulative Update from SP2 

Anyone who was facing the same issue or any thoughts on how to fix this issue? 

Best regards
Lukas
