Fabric datawarehouse to Power BI errors

Hi - I am experimenting with a Fabric dataware house as the source for my Power BI report.  I am getting an error when trying to create a relationship between 2 simple tables in the datawarehouse

Underlying Error: {"code":"InvalidOperationException","message":"We should never have pending changes here."}

I am also struggling to get schema changes to tables to reflect in the power BI report. If I delete a table or view it does not update the Power BI report data even after refresh and restart.

Anyone else finding datawarehouse a little buggy??  I am spending more time trying to understand what is going wrong than I am writing reports.
