Advanced Technical Support0Xfinity Stream Sign0In Failure

I have been trying for several weeks to resolve an ongoing problem signing into the Xfinity Stream app on my television.

I have already worked with Xfinity Assistant AI, live customer service, multiple levels of supervisors, advanced technical support by phone, an in-home technician, and an Xfinity store.

Despite all these efforts, I am still unable to sign in.

I am requesting escalation to an advanced technical team or someone who can investigate this authentication problem beyond the routine troubleshooting steps already performed.

I would appreciate an invitation to communicate privately with Xfinity Support so this issue can be investigated further.
