Articulate Quiz Problem

Hi everyone.

Can someone please help me out here?

I have built this Storyline e-learning course which has this quiz at the end. This course has been uploaded to an LMS for testing. When I tested this and do the assessment, one of the key specific tests that we do, is to close the assessment midway after answering let's say 5 out of 10 questions and then relaunching the course, it just goes to a blank white screen. In other words, it doesn't go to question6!

Have any of you come across this malfunction before?

Thanks in advance

Keith
