When an instructor changes the Until Date and extends a quiz, any student that has already started that quiz does not get the advantage of the new due date. The student that started the quiz with the original due date will see Canvas auto-submit their quiz when the first, original due date arrives. Can you program this differently so the students in progress can also have that additional time? Or put another way; why doesn't Canvas see students in progress to extend their time? I know the clock is already ticking but faculty would like to extend the time to all students not just those that haven't started.
