Hello, we are experiencing the same problem described in this post. We are adding apple login to an existent app. When we try to enable a new Service ID (for web) we see an error "This request is forbidden for security reasons. The bundle is not a primary App." but of course it is! We've tried to contact Apple support but, at the moment, they simple forwarded the request from one department to another without any solution. Is someone else going on or do you know how to fix it? Thanks
