Apple TV search function
Is there a search function in Apple TV when accessing it on a web page?
MacBook Pro
The website tv.apple.com currently doesn’t have a text search function.
Note that the site accesses Apple TV+ content only, all of which is shown on the home page.
The real Apple TV app on devices has much more (iTunes Store movies (buy or rent) and premium third party channels (subscriptions)), and includes a Search field.
