Subscription Apple TV+
If I subscribe to Apple TV +, what do I get? Can I watch all movies on Apple TV +? Including movies that are rented or bought, whether including also if I subscribe to this Apple TV +? Thank you.
A subscription to Apple TV+ (note the plus!) gives you access to Apple TV+ channel content, i.e. the Apple Originals.
It does not give automatic access to other content through the unfortunately similarly named Apple TV app.
If you see titles for Buy or Rent, then those would probably be iTunes Store content, which is not included with the subscription.
