Similar to competitor products, e.g. uphex/plai, there is an agency-level dashboard showing the performance metrics of all ads for all subaccounts in one place.
This allows the agency staff / media buyers to view the performance of all ads in one place, make any necessary changes, and see the higher/lower performing ads.
This is because often the agency owner is a different user to the media buyer / CSM and therefore should not necessarily have full agency permissions, but needs to be able to access all subaccounts ad managers.
