How do I successfully swap Truebit?

Hello, everyone. Let me start by saying I am NOT. tekkie.

I have tried many times to swap from Truebit to anything, like ETH or Link. The ‘first’ swap button works, and goes through the motions, then arrives at an offer to choose, then the ‘second’ swap button does not work.

What am I doing wrong? how do I work around this?
