My app dynamically generates manifest.json for each user, so that there can be multiple homescreen shortcuts, each pointing to the user’s unique start_url. However, in case of a server error (and other cases), I’d like to have a link that lets the user go back to the initial page for that PWA. And because of the way that the app is designed, I can’t use any information provided by the server (session, cookies, etc.) — this has to be done purely in Javascript inside the PWA itself.

It’s easy enough to do in iOS, since PWAs are isolated, and have their own sandboxed localstorage. That way, I can save the initial URL into localstorage, and then retrieve it when needed.

But on Android, PWAs share their space with each other and the browser, so I can’t find any unique way that I can identify each of the PWAs
