Incorrect score using Tin Can API when course resumed
I would be grateful for any suggestions to resolve a scoring issue on a course I have changed to Tin Can LMS output rather than Scorm 1.2. I needed to change the reporting API as the send data limit in Scorm 1.2 was causing the course to freeze when learners were closing & resuming the course.
Now on testing the Tin Can course when closing the course & resuming in the LMS a few times, the quiz results are not giving the correct calculation. It is like they haven't been communicated before the course window is closed. I have tested in Talent LMS & Scorm Cloud with the same result. I have tested when the course window is not closed/course is not resumed & get completely accurate results.
Any ideas out there to solve this? Is it a Tin Can only issue?
