Users are stuck in the last few sections of the course

Most every app or program or website that runs into a problem freezes, so unfortunately I don't know your posts describes the underlying issue.

With user problems in eLearning, the content itself is usually the issue, such as an incorrect trigger or a badly designed slide. There are a million ways for a designer or developer to break a perfectly functioning project.

I don't expect you're able to share any files people can look at or diagnose? The browser console sometimes provides descriptions of problems, but the average user won't know to look there or how to interpret it. Without much more though, this does kind of seem like me audio-calling my friend to ask if he likes my tie: he can try to offer an opinion, but the devil's in the details.

Edit: I'd also love to know how this click-based LMS memory supposedly works. It makes zero sense to me, though I'm still a novice with them. Does someone at your org think our Storyline content sends some sort of "click" to an LMS? What would that even accomplish?
