Users are /very/ not used to how to install PWAs to their home screen. Also, in the EU it just opens the site up in your browser, no lack of browser UI like you'd expect. Apple is wonderful. Edit: It seems I never got the news they reversed course on that particular idea of theirs.
I’m in the EU, and adding a website to Home Screen does hide the browser feel. Maybe this experience is different in different European jurisdictions. Your point about users not being used to this is very real. I didn’t know you could until some app author showed me. It really is as simple as sharing a link or copy-pasting, but if you don’t know it’s a think, it disappears into obscurity in the menus.
