For course progress issues, kindly ask the user to provide a screenshot of the issue so that you may advise on possible action items the user may be missing and so that you're able to identify the section of the course in order to test it, if you're able to access the course on your end.

If the issue persists after testing and troubleshooting, please escalate it.

I'm sorry to hear you're experiencing issues progressing through the course. So we can best assist you, could you please provide a screenshot of the slide/section that you're not able to proceed from?
