Access Not Authorized – Xfinity ID not recognized as an Xfinity user

Hello, I am the primary account holder and I currently have active Xfinity Internet and Xfinity Mobile service with 3 mobile lines.

When I sign in to my Xfinity account, I receive this message:

“Access not Authorized. You signed in successfully, but you must be an Xfinity user to enjoy this service.”

I am definitely an active Xfinity customer. I have already tried signing out and back in, using Safari, using the Xfinity app, reinstalling the app, clearing browser data, and trying different devices/browsers. I also contacted Xfinity customer service by phone, but they were unable to resolve the issue.

Please check the backend association of my Xfinity ID with my active Internet account and verify that my Xfinity ID is correctly listed as the Primary User/Account Holder. Please also check for any linked-account or profile association issue.

I need access to my account and I do not want to cancel my existing Internet or Xfinity Mobile services.
