Hello Frank,
Sorry to hear that you ran into this snag!
Looks like you've already tested the issue quite a bit on your end. I went ahead and opened a support case on your behalf so our support engineers can do further testing to see why your courses are not working properly when published using the most recent versions of Storyline 3. One of the troubleshooting steps that will be recommended is to test the behavior in SCORM Cloud. Here's how to test this behavior if you want to do this ahead.
Your case is in good hands, and someone from our team will be in touch with you shortly!
