Spot on. I've been using an iPad Pro for 3 years now I use it every day and I love it but I still can't reliably get two apps to sit side-by side on the screen.
I just got an iPad Pro and I agree this gesture is awkward. Plus, some apps seem to not support it at all, so it’ll silently fail when one of those apps is on either side.
Maybe if I used the feature more. But the only time I use it is with a somewhat older large iPad that I sometimes use for drawing but which mostly sits in my kitchen to display recipes. I can never remember the right incantations when I try to do the split screen thing. And don't even try on the smaller iPad I use day to day.
