Netflix App not working on Apple TV. Receiving "Sorry, we had trouble logging you in" errors
My Netflix app for my Apple TV has stopped working for reasons I don't know. The account works fine on every other platform I have, just not my Apple TV.
When I try to use my login information, I get a "Sorry, we had trouble logging you in" error message. If I try to "Restore Purchase" instead, I get an "Error. Sorry, something went wrong" message.
Things I have tried:
Un-installing and re-installing the Netflix app.
Restarting my Apple TV.
Step #1, then #2, then Reinstalling.
So far, nothing is working. Again, the Netflix app works on my phone, via my Playstation, via my smart TV. It's only the Apple TV box where it's not working.
It's a Model A1625, running 16.5 tvOS.
