Apple TV 4K Region Problem

Does anyone know if there is a current problem with the Apple TV 4K incorrectly identifying your region for viewing movies or TV shows via TV or TV+? I finished watching one show and then suddenly it refused to let me watch anything else—says it isn’t available for viewing in my region. I am in the US. My region didn’t

change between shows, nor did any of my settings. I have tried everything to get this sorted out, to include a factory reset of the Apple TV 4K, unplugging it and plugging it back in, signing out and back into iTunes and the App Store, and rebooting my phone, all without success. Notably, this has not happened to my Apple TV HD and I can also watch everything just fine on my iPhone. The Netflix and Prime Video apps on my Apple TV 4K also have no problem with my region. It is only affecting anything (and everything) I try to watch through TV or TV+.

I am at a loss for anything else to try to fix this and would appreciate any suggestions. Thanks.
