+After you add a user to a Managed Grafana's built-in RBAC role, such as Grafana Viewer, you don't see that user listed in the Grafana's **Configuration** UI page right away. This behavior is *by design*. Managed Grafana's RBAC roles are stored in the Azure AD (AAD). For performance reasons, Managed Grafana doesn't automatically synchronize users assigned to the built-in roles to every instance. There is no notification for changes in RBAC assignments. Querying AAD periodically to get current assignments adds much extra load to the AAD service.
