Access Overlap/ Unused Signal Report as Experience Cloud admin
Why are some Audience Manager reports missing when logged in through the Experience cloud, such as Overlap and Unused Signals reports even though the user is an admin?

Even though Audience Manager is part of the Experience Cloud, the permissions that have been configured for users within the Experience Cloud are different. Even though the user is administrator within the Audience Manager product contexts in the Experience Cloud, the account should be configured as an administrator within the Audience Manager Administration.

Contact your existing Audience Manager admin or Adobe Customer Care for the change.
