Issue
If you are having access issues in Audience Manager, despite being granted access via the Admin Console, these steps will help.
Solution
The AAM system admin, within the Audience Manager UI itself (not Admin Console), can complete these steps to grant full, escalated admin permissions within the Audience Manager UI.
RBAC controls can also be utilized to grant more granular permissions.
More details on RBAC available here: Administration (RBAC Controls) in the Adobe Audience Manager User Guide.
Steps to grant AAM System Admin permissions
Navigate to Administration Users.
Locate the user account in question, and enable the Is Admin checkbox to grant full AAM permissions.
