Is there a timer or time limit set for this course either in your AU’s Information ribbon or LMS settings? I’d submit a support ticket (there’s a button on the right-hand side of the page to take you to the website). The Support team is able to screen share with you while in your course on your LMS.
Another question. You mentioned that it “Seems like it stops logging after each page.” Can you elaborate? Is the lesson closing after each page? What is making you think that it is logging anything at all, is there a cumulative time stored in your LMS for this lesson are does it show 00:00:00.0?
