Keep the app cost separate
A player subscription and a content subscription can be separate purchases. Record both in your AUD comparison, including any renewal. Installing a player alone does not confirm channel access. Use the trial to test the combination before you agree to a term.
Use a real evening programme
Choose a familiar broadcast and switch between the live picture, guide and a second feed. Try the audio through your usual television or receiver. If your household uses captions, test them on the specific content and player rather than relying on a generic settings menu.
If phone playback works but Apple TV does not
Compare the player and connection type on the two devices. Confirm that the first device has stopped playback before starting another on a one-screen trial. A device-to-device difference is useful diagnostic information, but it does not establish the cause on its own.
