Had problems on minibits too, the app probably needs to be switched to the foreground to process the nwc messages. The coinos wallet nwc works fine for me for zapping. 

 How do you connect the coinos wallet to minibits? 

 Coinos the your nostr client with nwc i mean for sending zaps. And Coinos also gives you an lnaddress for receiving zaps. 

 Yeah. I don't know how to add NWC to coinos yet. I don't see the option i. The settings.  

 Click profile details on the main page… took me while to find too 

 Thanks. I see it now!
