For those experiencing the #Coinos "Unable to send zap" error:
We've revoked some NWC connection secrets due to concerns of a security leak. This affects NWC connections that were created before Feb. 19 2025.
If you're having trouble zapping from Coinos via NWC please visit https://coinos.io/settings/nostr to create a new NWC connection and then copy the new connection string into your Nostr app.

Thanks. I just ran into this.
