Hello @cu_denmark00 ,
Have you tried to use a different browser on your desktop? Since it works when using Safari on your iPad, I recommend using a different browser on your desktop as well as clearing your cache and cookies of your current browser to make sure it is working properly. If after clearing the cache and cookies of your browser you are still experiencing this behavior, I recommend reaching out to Canvas support so that they can investigate your specific account.
Here are our guides for either a Mac or PC that will walk you through clearing your cache and cookies.
