I have applied for the three courses here and due to some reasons I've missed my deadlines. Yesterday, I've reset my deadlines for all three courses. After completing my 1st week and its quiz, when I've reached to week 2nd it was showing the quiz is locked and I can't access it. And this happened with all my three courses. When I've checked the issue, it is showing that the "item is blocked by instructor".
Please guide me with some solution.
