So just right now, I was watching a YouTube video in splitscreen, and using Safari in the other screen on my gen 1 iPad Pro 12.9”. Somehow, I accidentally tapped something between the two screens and they instantly swapped places. This could be useful for me on a day to day basis, but I cannot figure out how to replicate this. I tried googling but it didn’t turn up for me. Does anyone know how this was done? Also, does anyone know if it’s possible to make splitscreen the way it was pre iOS 11, where you just swipe left from the right side of the screen and the second screen will come out? I kind of hate the having to drag a new window from the dock then having to place it and then expanding into splitscreen. It’s tedious. Anyone have a solution? Thanks for the help!
