testing zaps for this note… we made six attempts to⚡zap this note, at optech@fountain.fm, over a period of 29 minutes. six of the zaps were successfully paid... please check for 6 satoshis received. however, we did find that only four of the payments produced zap receipts in time for our server to recognize them. this is a problem because the user who zapped you would not see an active ⚡icon after zapping. they might think the zap failed, and therefore might not zap you again.... also.... your average zap time was 20836ms (20.8 seconds). we consider this zap time slow... if possible, zaps should be confirmed in under two seconds. (if time is too slow, other nostr users might think your zaps are broken, might not zap you again.) 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.
