Hi, Ben! Thanks for the quick reply.

I read that 'how to track your progress' article previously. I've tried the 'completed' button, both at the lesson and module level, and in both Safari and Firefox (both on macOS). But it doesn't seem to actually work.

The page updates when I click the button (i.e.: the 'progress' bar is removed) but, if I then navigate to another page and come back, the progress bar reappears. If I go to the 'Progress' page and click on View More=> completed, there are no completed lessons found.

I've tried clicking on completed for as many as eight or nine lessons: none show up as 'completed', and my over-all progress for Guitar Fundamentals 1 remains stubbornly stuck at 0%.
