Quoting from “YouTube is (finally) Coming to Horizon Home Making it Easier to Watch with Friends”:
Meta announced that Quest users will soon be able to watch YouTube content inside Horizon Home, the first-party social VR space that’s finally making it easy to hang out in VR with friends.
This article is a year old. Is that feature already there and I‘m just not seeing it?
As Mozingo pointed out, Horizon Home isn’t the same thing as Horizon Worlds. Home is just the home environment where you launch games or people pop up when you’re on a call.
Ooooh my bad!
