Hi - I'm in a perpetual loop with the test for the customize chatter experience module.  After completing the test and pressing submit, the green submit button just spins with the 3-blocks showing it's evaluating my answers, but then it gives no feedback, no wrong answers, etc.  Any suggestions?

Trailhead Check Challenge Button is not responding back with results.
