I was able to send it to myself. I also zapped you 33 sats. Do you see it in your wallet? You have to add the minibits mint. "Add mint" and "add minibits mint". No idea if your sats will just show up in there or if you had to have it added first. 

 Yes I will send 33 back as a test.

I was able to zap my own note for ecash as well instantly.  

 I recieved it. Thanks! 

 I just tried sending you some sats directly through the private tab in minibits 

 I see a 20 sat 
I also see a 20 sat error
