    Hi MTerkait,

    The reload is not something Power BI is trying to do on purpose for the user. In the newer build, Power BI is checking RLS more strictly when the report loads. If RLS exists and the user is not part of any role, the security check fails and Power BI returns a 401 unauthorized response. Because the dataset load fails at that point, the report viewer retries loading the report, which is why you see the page refreshing continuously. Earlier versions handled this more gracefully by keeping the page loaded and showing restricted visuals, but now the failure happens earlier during the load process. There is no additional benefit or new functionality intended from this behavior. As per current Power BI guidance, when RLS is defined, all users must be assigned to at least one role, and doing that avoids the reload issue.
