This is the second time I have logged into Canvas to take a quiz and the instruction appear at the top of the page but none of the question appear so I can't take the quiz. I have tried a MacBook and a Window PC, I have tried Chrome and MS Edge, nothing seems to work. I have been able to see and complete other tests so this does not happen all the time. I need help. I don't want to get a 0 on this quiz.
