A check for Apple TV
If you are comparing access to a single film, open its detail page and identify which offer the app displays under your account. For a hardware problem, check the Apple TV model and tvOS instead. An HDMI problem with a box can occur while the same title plays in a supported smart-TV app.
Check on the intended screen
Open the app catalogue on your actual device and confirm the publisher and region. Sign in only through the service or documented billing issuer.
Keep a title-level test
Use one title, episode or fixture that you can identify. Record whether the app launches, the account signs in and the item plays.
