Trouble with course saving progress in microlearning Rise courses.

What is the trick to get a microlearning course in Rise to save the learner's progress? I can't seem to find anything in the publishing settings, and adding Continue buttons to each section doesn't seem to work. No matter how far I've progressed through the course, it just starts me at the beginning again if I exit and re-enter.

And if you're wondering if it's an LMS issue, I already submitted the problem to my LMS support team and they said they isolated the issue to the SCORM file and not the platform.
