Nike Training Club stopped streaming through Apple TV
Starting May of 2021, Whenever I tried to stream a class-based workout through my AppleTV, got the message "An error occurred loading this content. Try again later." However, time-based workouts worked.
This year, however, Nike eliminated time-based workouts so the entire app gives me that message.
I have contacted Nike on dozens of occasions, via twitter, etc, and either been ghosted, or referred to an "Elite team" and then ghosted. They have abandoned all support.
