ATLAS Course Broken
A course on ATLAS is bugged and cannot be completed. At chapter 3 your answer cannot be submitted. I don't know who can fix this but I thought I'd post this here.
I would suggest to seek Apple contact information on the ATLAS site itself. This user-to-user forum is far too generic and consumer oriented for the subject of Apple Technical Learning Administration System, and Apple QA doesn’t look here for any feedback.
