You can't switch owners of shared family purchases on an iPhone. You need to rebuy the apps under a new family owner after dissolving the previously family which is not easy or seamless.
Plex picture uploads don't work in the background on Apple so you constantly have to take the screen to keep it active.
Basically if you like having someone else make all your design decisions for you Apple is actually a great way to go. Defaults are generally sane, but if you run into something that they haven't sorted out yet, it's going to be painful and you won't be able to fix it. My wife and daughter love their iPhones. Apple generally curates their software well and there's a good chunk of great software only available on Apple. I was constantly fighting with mine to get it the way I wanted and in the end I have up and bought a Samsung Galaxy phone. I could do what I wanted almost immediately and have had no issues. I can't remember if Apple has the ability to add a swipe keyboard either. My wife is always jealous of mine.
