Same here - I had to reread the parent comment because I have a Roku too and that's the behavior so that's what I expect...?

That's a reasonable expectation, not having ever used Apple TV though that isn't mine. Having only ever been on the Roku platform, my perception is that it's localized.

As an apple tv user, it has been trained into me that voice commands are Global unless specifically in the search field (not just the search screen). I fuck this up all the time.

What is naturally intuitive to me is to go to an app and anywhere in that app have a voice search specific for that app, as Google is requesting of Roku.

I hate the voice search on AppleTV for this very reason. I so wish that voice would just search within the app I am using instead of sending me to the itunes store or somewhere else. Why make me click and swipe extra times to get to the specific app search box...? If I want to search globally, I could just hit the home button and then search!

It sounds like Roku is upset that YouTube is asking them to prioritize YouTube results in exactly this case.
