I get a permission request in Amber eventually (takes many minutes) but the PWA of jumble doesn't seem to get the response back from Amber.

My guess right now is the OS (GrapheneOS) is "unloading" the PWA or something and the websocket jumble need for the auth response is closed.

(Probably similar issue with how the cashu.me PWA needs to be opened just before trying to NWC zapping in Amethyst otherwise the request never gets to cashu.me )
