Due to canvas not uploading my PDFs properly through Chrome, my teacher suggested I use Firefox (I do not use Internet Explorer). When I get onto canvas through firefox, there is no submit assignment button at all. I'm making sure the assignment dropboxes are open for submissions, but there is no button loading, nor does it show my previous submissions.
What is causing this issue? Can it be fixed? I cannot use Chrome or IE, is this a computer issue?
I have attached an image of what my screen looks like, thank you.
