Hi,
I logged in front-end with that user account, but I can replicate the issue. I can access the lessons up to "M8 Bagua " module, all quizzes up to that module are passed.
In that module, the quiz is not passed and the rest of the lessons are not available.
For open module in lesson page, when user click on next, you can set this option - "Skip modules pages" to "Yes", from course edit page, from admin.
Kind Regards,
Alin
