When I login to canvas, the dashboard page is blank or the corse cards are flickering between white and gray. Like they are loading but nothing comes up. I can't even click on the course card to take me to my classes. Then, once I am in my courses, the only tab I can see anything at all is my modules tab. That is blank sometimes as well. Nothing seems to be fixing the problem. I can not even submit assignments because I can not get to where I need to to submit them. What can I do to fix this as soon as possible? I even ran a scan and the Mac came back clean so????
