Hi,

For the past hour I have not been able to successfully submit my responses for the trailhead unit "Get Started with Service Cloud for Lightning Experience  Service Cloud Transition to Lightning Experience".   After clicking the green button to submit my answers the button shows an indeterminate progress bar animation (moving dots) but does not tally the results of my quiz.

Trailhead Check Challenge Button is not responding back with results.

Check Challenge Button Not Working in Trailhead Since Morning. Request tp provide the ETA when it would be available again ??
