I don’t get this? I was just watching YouTube on my iPhone and the notch never covers any of the UI elements in either portrait or landscape? In portrait mode it’s got the clock and wifi elements on either side of the notch and when watching videos in landscape both sides of the phone are just black bars including the notch. Edit: Even zooming in on the video doesn’t hide UI elements only whatever portion of the video overlaps the notch.
