In the October Keynote at about 51:00 into it when talking about multitasking, it appears as though he is pulling a Messages banner notification down into a Split View. Though I’ve never heard of this, I’ve rewatched this part of the video several times and unless I’m seeing things, that is what he is doing. I am on iOS 12.1 and have tried this several times, but cannot get this to work. I am, though, only on the original 12.9 iPad Pro so maybe it takes a newer iPad? Did anyone else notice this during the Keynote? Does this work for anyone?
