PBI Gen2 Capacity Metrics Analysis cannot connect to data anymore since App update

My monitoring dashboard from the app Power BI Premium Capacity Utilization and Metrics for Gen2 worked fine two days ago, showing data for all of my 5 Premium capacities (even if quite slow on most visuals).
I made the app update that was pushed in notifications yesterday for Version 12 and now my data cannot be retrieved and I cannot see anything anymore!

The error that shows is : Information is needed in order to combine data;Information about a data source is required.. The exception was raised by the IDataReader interface. Please review the error message and provider documentation for further information and corrective action. Table: Metrics_by_7_day.

I tried changing the capaicty ID in parameters, but this doesn't change anything.
Is there another way to reconnect my capacities and refresh the dataset so that the report works again? 

Thank you for your help!
