Hi,

When attempting to drag and drop an option in mobile browser, the page is scrolling along with option. This is making hard to answer the question. We found the below web console error while using a drag and drop question.

"[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/5093566007214080"

Please check attached screenshot.

Using below version moodle:

Moodle 3.6.6+ (Build: 20190913)

Do you get the same error on the Moodle demo site? https://qa.moodledemo.net/mod/quiz/view.php?id=31

Hmm. It does not do it for me in any desktop browser. That makes it annoying to debug. triste

When we implemented these question types, we did test on mobile devices. And the quiz on qa.moodledemo.net is working fine on my iPhone. I don't have an android device to test with.
