Not sure if you did something else or if it took a while to propagate the changes but I’m seeing the following address now.

In settings, you can set a username. 
Ok awesome! Thank you for that! Sweet.
No prob! Lightning address looks good now. Only issue now is that your profile got inadvertently reset (no profile pic and bio). I think nostr:npub13pnmakf738yn6rv2ex9jgs7924renmderyp5d9rtztsr7ymxg3gqej06vw also ran into this issue. Maybe nostr:npub12ekpvme6m2cv37a9mgq4kzemej8tx6ttg40j582rh77ewpvkg65qj8tq0f can look into this when he gets a chance. 🤙
Also, received your zap. Here’s to more reliable zapping. 🍻
