What I have learned today about NOSTR: Enter Lightening Address in "Edit profile", not Settings (I thought it would be automatically synced between alby and client, it is not). Hard to find "edit profile" - in iris.to three gray dots on profile page, in public Damus app (in contrast to testflight app) I could find no option at all. LNURL may cause issues, it seems to be better to enter a lightning address. Zap data for posts inconsistent in client (or delays).
