Sold bitcoin. Buyer hasn't paid and isn't responding

Hello, over 12 hrs ago someone bought some BTC of mine with Zelle. He hasn’t paid and isn’t responding in chat. It says Remaining time: 3 days, 15 hours under Trade Information. Do I really have to wait that long for a resolution?

Yes, at that time it will be possible for you to open mediation from the GUI.

To favor security, Bisq trades aren’t very quick when a peer is not very cooperative.
