Hmm, I’ve tried multiple times but haven’t been able to get an invoice from Blitz Wallet via NWC, so I haven’t been able to fully test it. However, everything works as expected when using Alby’s NWC.

Based on your description — when you created the NWC in Blitz, did you enable the “lookup invoice” option? That’s required for checking whether a payment has been completed.

Also, I’d suggest nostr:nprofile1qqsvdc3s5f0260zfwqfkx7lnw77wmqw8ekmqmzq6v0kmzw9s32ngpqcfwuxkg not using wss://relay.damus.io as your NWC relay. That relay has strict rate-limiting and isn’t ideal for NWC usage.
