I am a student using Canvas, and the last few days have been pretty rough. I am able to log onto my account and my classes pop up, but when I click on a class and go to do an assignment all I see are three of the boxes they are all white and loading. They have been loading for days. I restarted my laptop, cleared all my browsing data and cookies and still nothing. My brother is also using canvas but he can access stuff. I tried logging onto his account on my computar but it is still not working. What is going on???
