Can anyone help me out?

I linked my Npub into Mutiny and also linked Mutiny into Damus, but zaps aren’t working when I try them in Damus, but doesn’t give me an error message and zaps aren’t being subtracted from my Mutiny balance so looks like they are not going through. 

Any suggestions are greatly appreciated. 

 Mutiny has to be open in order for the lightning channel to be online before you can zap. Idk if that helps.
