The Apple TV app on iOS, iPadOS, macOS, and tvOS has been updated to bring Apple TV+ its own dedicated “Originals” tab. Users on the most recent software version should have access to it, and if you don’t, just close and reopen the app.
On the Apple TV app, you can rent and buy shows and movies, keep track of the shows you’re watching across most other streaming services (notably excluding Netflix), and of course watch Apple TV+ if you have a subscription. It could understandably be confusing for some people, and this update should make it easier for people to find the Apple TV+ streaming service.
This update comes with the release of iOS 14.3, and also includes Apple Fitness+.
