The Table Service Certification course has been renamed to Table Service Certification- Legacy. This doesn't effect the course in any way, it still works the same today as it did yesterday. You will just access your course by clicking the new name, Table Service Certification- Legacy. If you would like to get signed up for the new course I would be happy to do that for you, just send me an email to email@example.com.
I just got done rebuilding the way that the videos are shown and the quizzes are taken. There should no longer be an issue with pop-ups disabling the videos.
If you have any questions or comments feel free to let me know,
