Not sure this is the right forum, but...
Is anyone having trouble assigning DirecTV as your TV provider on an AppleTV 4K? Two of my three were still using the former Spectrum login from before I switched back. I'm getting error code 205.4 when I try to login with my DTV account. Neither Apple nor DirecTV have been helpful on the phone, so I thought I'd bring it to the experts.
