Ownership/app role assignments for SPN created in Corp tenant

Hello Austin Hobbs,

As discussed offline, the issue occurred because ownership of the App Registration in the PME tenant does not automatically grant permission to manage the corresponding Enterprise Application or app role assignments in the CORP tenant.

To resolve the issue, you need to work with the appropriate tenant administrators. A user with the Application Administrator or Global Administrator role can add you as an owner of the Enterprise Application or grant the required permissions needed to manage the application and its app role assignments. Once the necessary access is assigned, you will be able to perform the required administrative actions.
