> Multitasking is a prime example: I end up using my girlfriends iPad Pro about once a week, and for the past year I have not managed to internalize how to reliably manage split screen modes and the like.

I'm still shocked that they haven't done anything to solve or improve this. I love the idea of side by side apps but it's always so hard to remember the voodoo needed to summon it. There's also the problem that I can never remember which apps don't support it.
