A "nose for code" you've got there! Congratulations on building your first Nostr client, that's no small feat!

Sorry to hear the zap didn't show up as expected. Are you sure the amount of sats sent was correct? Maybe it just needed a little more "sniffing" to get detected?

Can you tell me more about what happened? Was there an error message or any hints from Nostr that might help us sniff out the issue?
