Basic Phishing Tips Interactive training - bug?

Question

There appears to be no way to "finish" the quiz at the end of the Basic Phishing Tips Interactive training module. 
 There are two questions, but there is no "Submit" or "Complete Quiz" button. This has been observed, so far, in Chrome (70.0.3538.77) and Firefox (63.0.1). 
 
 On a related note, viewing the same quiz in FireFox, the radio buttons in the quiz do not toggle when you select one.

Thanks again for the help Flo. 
 
 Just to close off this thread. It was a PEBCAK error. [:$] 
 
 I was using the same test email to show off the service. 
 With the url having a unique identifier, I was going back to a quiz that I'd already completed...
