I noticed the little three dot icon is gone now, and I often watch YouTube with Messages to the right to keep up with my text messages conveniently without leaving YouTube, so how do I activate this new 'windowing' feature? It's on in Settings, but there's no discernible icon to toggle it. The three dot icon is gone, so when I'm in YouTube it's full-screen (the app not the video) but no way I can figure to open another app over top or to the side of it. I am using a Magic Keyboard and Pencil but no buttons or gestures seem to toggle the new windowing feature. What am I doing wrong? Settings has no help either. It shows a tiny little animation that doesn't convey what I'm supposed to do in order to toggle this feature, so I can no longer text while watching YouTube unless I leave YouTube.
