Yes it was an on chain transaction. I had original tried to send via lightning but the transaction wouldn’t go through.

My friend isn’t into bitcoin that much. But when we hang together and get food one of us will pay cash and the other would get reimbursed with sats. Well yesterday he said just pay me back in cash, I asked him why and he said that he lost the sats he had in breez.
Roy from Breez here. Not sure what happened to your friend, but sats can't just disappear. If you sent an on-chain transaction and the swap failed, they should be refunded in Breez.
Please ask them to reach out to our support and we'll follow up: contact@breez.technology.
Thanks Roy! I just forwarded this message, I appreciate your help!
Sure thing. Apologies for the inconvenience, I'm sure we'll get to the bottom of this 🙏❤️
FYI here is a screenshot of his transaction history as you can see no outgoing transactions and 0 balance. 
I see... I think his channels got forced close for some reason. Maybe something useful in the warning?
I’ll have him check, I’m not sure if I clicked on that icon yesterday, maybe a banner message/ notification can help other users when an edge case like this happens! Happy to hear you guys are on it!
