PSA: If you use NWC and one tap zap, chances are some of your zaps are never paid. Since I have my own node, I can see a bunch of unpaid invoices for different sums, 21, 541, 1000, etc. If you really meant to zap some one, I suggest checking it later and see if it is registered. On the other hand, you save a lot on zaps and get the satisfaction of zapping without actually spending any sats! 🐶🐾🫡
