Courseware completed 100% halfway through

During chapter 11 courseware became unresponsive. Reloading it showed the couse
wrongly being 100% completed and inaccessible. I have several days left on the certification
subscription, should the courseware really be inaccessable after completion?

Actually it’s accessible!
Before it would pop up immidiately, but now I can still access it by clicking “Unity Certified Developer Courseware” next to Terms and Conditions.
