please I need your support.
Suddenly, the completion tracking has stopped working on quizzes even if nobody touched course/quiz settings in years.
1) Course tracking: enabled
2) Tracking settings:
3) Quiz tracking settings
As you can see from next picture, SCORM is completed while quiz is not (I passed with full grades many times, but still no blue flag inside box...)
I first thought about wrong settings, but here's the riddle:
a) quiz completion tracking worked in past
b) the behaviour is now randomic. Some users are flagged, and others not, even if they passed the test with full grades!
