Error on Adding new users to RLS - Power BI Premium

[ReinhardtScheun]

Struggling to add new users to a RLS role in a Premium workspace.

It either just loads and never finishes when you try to save or says that an error occured. This is only happening to one model. 

We have removed it and redone the publishing and same issue. 

Testing of the role on Desktop does not give errors.

You may keep an eye on the Awareness.

Power BI customers with premium capacities using Row Level Security may experience issues while adding external guest users (AAD B2B) to roles with the message, "The Role could not be updated. Please try again later". As a workaround, users can move their workspace to Shared, add the external guest user, then move it back to the capacity. Engineers have identified the issue and a fix is expected to be deployed by end-of-day 03/07/2021
