I was outputting my project to html and then previewing it in a browser and the advanced answer options weren't showing when answering the quiz. So my question still remains. Do the advanced answer options work in html?
Have a happy day 
I still have 8.0.3.290 installed along with 9, will double-check.
Just tried out with one MCQ, with one correct answer (only way to have advanced answer option working) and everything worked as expected for me when I Preview HTML in Browser. Then I published to HTML, and had another view: all OK.
Either it is due to my version of 8 or something is wrong on your side.
My setup:
- 4 answers
- Infinite attempts
- for the wrong answers: Show Feedback message and as action 'No action'
- for the correct answer: Show Feedback message (changed its color) and as action 'Continue'
