I have SCORM packages shared from Jhpiego/UNFPA which were also developed with APKs. Same courses work perfectly fine on Android devices tracking scores whereas the same courses do not track scores at all.
I would have attached the SCORM package but it is too large for attachment size provisioned.
I have 9 courses and all of them have the same issue in tracking performance.
Where are you looking for the results of the SCORM quizzes?
As an administrator, select the SCORM activities and you should see the SCORM reports tabs.
Moodle quiz reports is for quiz activities, not SCORM quizzes.
SCORM quiz results are within the SCORM content itself.
Yes the scores are supposed to be obtained from the SCORM packages but the quiz finish function does not seem to submit one's scores to Moodle.
