I zapped you now but not with my Coinos wallet! ,I think that to zap someone using Coinos it needs to create a new Nostr key with them, cause using your regular key from the other device or clients,it’s not possible,I don’t know why but I think this is the only explanation 🫠.

That seems like what’s happening. I wonder if the new key you create with coinos becomes your new private key? Or just a separate key to connect the wallet to nostr?
