We have a course in our LMS where I added a few slides and republished. The course is now loading and moving slowly. There was nothing fancy about the additional slides. They were just a freeform pick one and a freeform pick many.
The only other thing we can think of is that the earlier course was done in Storyline 3 and the updates were done in Storyline 360.
Would that cause the slowdown we're seeing?
