Haha, I don't know. Installed Alby Hub on Umbrel Home, that install process was very smooth! For some reason I cannot zap on Nostr with my Alby Extension, even though I did manage to zap someone with Alby Go iOS app, by scanning a QR code when clicking on a zap button on https://iris.to
Try going to you https://getalby.com/dashboard , log in and see if the extension gets reconnected to your Alby web Account. If problems persist, reach us at getalby.com/help -JP
