Spoke to Apple support…TVAPP-00144

Error TVAPP-00144 when trying to stream free channels like unsolved mysteries for example, according to Apple support supervisor, is a Xfinity app issue, not an Apple TV 4K issue. Xfinity support tier 2, keeps telling me it’s an Apple TV 4K device problem. Since the problem is related to 2 different tv guides, it can’t be on their end. Basically the tvgo channels are missing on the guide when using the. Finite app on the Apple TV 4K devices. Works properly on all other streaming device’s including iPhone and iPads. Anyone fix for this?
