OK here's a problem for you nostr gurus:
After noticing I don't receive zaps anymore I checked my profile and found that my zap address had changed to an unknown account @alby.com.

And I can't change it because whatever changes I make to my profile, aren't saved.

What's going on here, and how can I fix it? Running Damus beta. Thanks for any help!
