Dammit... I was hoping that was the problem. It makes sense, but it's irrelevant if you have funds in your account. Do you a Cashu account? That's another web-based wallet that offers NWC. If I were you, my next step in diagnosing the problem would be to go to cashu.me, create a wallet, authenticate with either browser extension or your nsec, and enable NWC. Plug the Cashu NWC into Damus and see if the problem goes away. If yes, you know the problem is with Coinos. If no, the problem is related specifically to Damus.
