Keynote split screen
I have recently purchased a MacBook Pro and I am transitioning from using my iPad Pro, while preaching, to using the new MacBook Pro. My problem is while using the MacBook Pro with Keynote and GoodNotes in a split screen. When I go to play the Keynote it takes over the whole screen on both the MacBook and the tv behind me and eliminates the split screen so I can no longer see my notes in Good Notes, unlike my iPad which will keep the split screen open on the iPad but only show the keynote on the TV screen behind me. Any ideas, thank you.
MacBook Pro (15-inch, 2017), iOS 12.1, null
