We used to be able to test the RLS of multiple reports that shared the same dataset by going into the dataset's options --> Security --> Test as Role to view main report as a specific user. I could then do to the panel on the left, and select a new report (that shared the same dataset), and it would allow me to view that report as the specified user as well.
However, starting last week, the option to select another report is no longer available. If I click on the workspace icon, it just redirects me to the workspace.
We really need this functionality to be brought back as there is no other way to test RLS for these reports now!
It's by design . If you feel that this change has had a greater impact on your operation, We'd love to hear your feedback at Power BI Ideas.
