I'm using SSAS Tabular, connected to dashboards on app.powerbi.com and am attempting to implement row-level security.
I've created Roles within the cube that restrict certain users based on a DAX filter. When they attempt to create a new dashboard, the security works. However, when they open a dashboard that had already been shared, the restrictions are not applied.
Additionally, I've tried creating a report in a Group Workspace, sharing it with a user, and then restricting that user's access through row-level security.
Is there any reason adding row-level security doesn't immediately take effect, and doesn't seem to be applied to dashboards that have already been shared?
