Coinos DOES in include the lud16 while Cashu does not. Since he's using the Coinos NWC string, the lud16 is overriding the LN address he has setup in his profile and zaps are going to Coinos instead of Cashu. With the manually updated Cashu connect string set as NWC, sending and receiving zaps should now go through Cashu as we intend. I'm just waiting for him to execute these instructions and we'll see if it works properly
