I wish Apple TV did that. It has a global search feature. My kids push the button on the side of the remote and say what they want to watch. Then they get a screen saying you can rent it for $6.99 or whatever, and I'm thinking "didn't you just watch that the other day, and I didn't have to approve any purchase..." Well of course Netflix doesn't appear in the Apple search results. You can search in their app separately, but it's not integrated into the system. Even if you pay all of the services their $15 a month or whatever, you still can't just watch what you want because something something engagement metrics. It's tiresome.
Isn’t that an issue with Netflix? I haven’t looked into the APIs, but I do know that HBO, Hulu and Disney content will show up in the Apple default search results.
Netflix and Amazon (maybe?) always require a separate journey
