Thanks for the information and the 6 sats.
I'm using lnd, I don't think it has any Nostr support, so I'm not sure how I would send zap receipts to relays.
testing zaps for this note… we made six attempts to⚡zap this note, at odt@pay.instant.gr, over a period of about 1 hour. Six of the zaps were successfully paid... please check for 6 satoshis received. problem: we found that your lightning address server **did not* properly produce zap receipts, and/or didn't send the zap receipts to the relays specified in the zap. (the zap spec requires that the zap receipts be sent to the relays specified in the zap.) this means a nostr user who zaps you might not see a number appearing next to the ⚡ icon after zapping.... if you wanted to fix this... you could try getting a free rizful lightning address -- https://rizful.com ... if u get it set up, pls reply here so we can do this ⚡zap test again.

yes -- zap receipts are quite complicated to try to add if you are rolling your own solution..
