try the Alby relay I assume it runs more reliable for NWC.
Discussion
K let me test
payment went through, but zap is not showing on the note. i think maybe cause the clients i'm using are not querying the alby relay for the zap receipts. i checked damus and primal. the alby relay is not on my relay list so that could be the problem. i don't think many people have the alby relay on their relay list.
the zap will not be on the alby relay. the alby relay is solely for NWC events (here paying a bolt11 invoices. - which does not know anything about being a zap)
the recipient publishes the zap to the relays set by the client as defined in the NIP57 spec.
