Adding/changing/removing a user's Content Editor role does not show up in the Role Membership history, because Content Editors belong to Groups, rather than having the role assigned/removed.To view a user's Role Membership History, a Platform Manager can:
- Navigate to Core.
- Select Users > Edit User Profile Data.
- Search/select the user.
- Scroll to the lower left under System Information > Role Membership.
- In the upper right corner, click the View History link.
