Debug a .story file
I could really use some help debugging a Storyline file.
The problem: some users (maybe 1 out of 100 or 1000, but still!) experience problems with my courses. The progress is lost. The courses are all built in the same template and the problem occurs with multiple courses, on different devices and browsers, for a couple of months now.
The user reports that he succesfully passed the exam ('Eindtoets') and had 7 or more out of 10 questions correct. The results screen also shows this, see the below screenshot from the user (PASSED-layer is shown):
However when I use her credentials to login and open the course, it shows that she had 0 out of 10 correct. The Results screen shows the FAILED-layer:
Also, the button for redoing the test is gone. Which is placed on the base layer of the results screen. Only when the user PASSES, the button to retake the test is hidden:
So how can the button disappear on the failed-layer?
The users report that the course is not finished and they do not get their certificate. When reopening the course, they get this failed layer on the Result screen, with no option to retake the test. They also report sometimes that other progress is also lost. It's like the course doesn't track the user's progress in some cases. I have included the .story file of one of the courses.
What's going on? Is it a browser issue? Internet issue? Any help would be greatly appreciated!
