Why am I seeing the error: "You do not have the required authorization to access this profile" when creating an ad?

This error occurs when the integration is linked to a user account that does not have the necessary permissions in Ad Manager. If another team member sets up the integration, their permissions determine what you can access.

To resolve this, check with the user who created the integration (or in your own account) and confirm that they have full access to the profile, not just read access. If their permissions are limited, they may need to update their access in Ad Manager or have someone with full permissions recreate the integration.
