When my students are quizzing in Canvas and they click on the button to quiz it will only open the quiz if they choose open in a new tab. It works fine for me. I checked out our browser basic settings and they seem to be the same. Is there a more obscure one I'm missing? I'd rather not have a new tab for the quiz because I like to have them get a one time view of the quiz. Tried with Safari and Chrome. Thanks.
