Is there a way to force Chrome to update the route on a PWA that has been installed before the routes changed, without having to uninstall and reinstall the app?
Because the PWA on my system now opens to the old route, and shows the elephant banging the keyboard because "The page you are looking for isn't here.".

Sadly, since there is no link to the actual home route on that 404 page, and no address bar on a Chrome PWA, that means you are basically stuck.

It seems that web-manifest will be updated on next start and new routes will be applied (on latest chrome as of today). There seems to be no way to force update the icon, though.
