Can’t see Apple tv+ video catalog

The TV app on iPhone or iPad needs internet access, to show anything other than the local library.

• Through Wi-Fi, the TV app should have regular internet access.
• On cellular, the TV app would need extra permission to use cellular data. Settings﹥Cellular﹥[scroll down to apps list] TV app﹥

On what device do you have the Apple TV app, or are you trying to watch it?

The Apple TV+ subscription service gives you access to the Apple TV+ catalog of movies and TV shows, also known as Apple Originals — content that is not available elsewhere.

This is different from the iTunes Store catalog of movies and TV shows. The content there is for buy or rent. This content would show in the Store tab of the Apple TV app, and the purchased items from there would show in the Library tab of the Apple TV app.

Additionally, some third party devices get the full Apple TV app (Apple TV+, iTunes Store, in-app Channels), and some other third party devices get the Apple TV+ app (just Apple TV+ content).
