I need to finally solve this issue: when logging in to Jumble (npub17n4…fyh9) via a Citrine (npub1hql…gspw) localhost bunker I get this Amber (npub1am3…xrv7) error and I can't sign any notes. If I use a strfry localhost bunker it works fine but other web clients work fine with Citrine (for example noStrudel) so I'm not exactly sure where the problem is. How can we debug this?
