It is a limitation of a PWA. A native app (wrapper) will likely be coming though, and a custom Capacitor plugin could theoretically interface with the native API to switch out icons. Theoretically. No promises though :)

    • scroll-to-top doesn’t work
    • back swipe is unreliable (works 30% of the time)
    • after going back you have to wait a second before you can scroll
    • no app icons packs
    • no haptics
    • text select doesn’t work if you immediately go down since it scrolls the page instead

    Don’t get me wrong, it’s still impressive. But I‘m very aware that it’s a web app and I have to step carefully. These might be small things, but they’re constantly annoying me.
