Actually the iphone was planned to use PWAs in the start, but Steve Jobs switched to native apps after realizing that performance and usability was going to be poor. He was right and still is. Not that it's impossible to implement a good PWA, all you have to do is manage your state and interface in a way that no interaction takes longer than 50ms to compute. But most developers are not able to deliver than, most don't even think about UIs in this sort of way. And V8 GC behaviour is still terrible and an unbelievable battery hog.
