OK @Jordi Llonch Esteve, I’ve got an update for you. I completely removed and reinstalled the Alby extension. I was still unable to sign in. Then I opened another Chrome profile and installed keys.band and tried to sign in using the same Nostr profile. It also didn’t work. Then I tried with a completely different Nostr profile using Alby, and was able to sign in with that one. So, as far as I can tell, Satlantis doesn’t work with my specific npub, because…reasons. Hope that’s enough info for your team to investigate.
