How come I can only watch one episode of invasion on Apple plus TV then I won’t let me watch the next one, but I can watch the second episode on my phone or on my iPad but not my TV

For users that are not signed in to the Apple TV app on their smart TV, the Apple TV+ service may allow select first episodes, as a sort of teaser.

Verify that you are signed in to the Apple TV app, through the in-app Settings (sprockets wheel icon), using the matching Apple ID account.

Get error message, "connection not available" when attempting to watch second episode of a series.

Inconsistent screen messages:

Subscribe to Apple + and subscribed in a different part of the screen. I use a Amazon fire TV stick as the connection via the app. Please help

If your Fire TV system software is up-to-date, and the app is up-to-date, and you have tried a restart of the device, then please contact the Apple Support staff for further assistance.
