If you’re a DirecTV subscriber and trying to watch TV shows on iOS/iPad OS/TV OS, you may have encountered an error when trying to log into DirecTV. Individual channel apps may ask you if you want to Link your TV Provider to the app and if you select “Yes”, you will be presented with a login screen for DirecTV.
Unfortunately, the API version of the login screen has some kind of error (probably an encryption mismatch) and will give you an error saying
That User ID doesn't seem to work here. Please sign in with a different ID. Care Code 205.4
