I am not sure why, but sometimes Canvas and Crocodoc allow me to attach a Word document to my comments section in response to a student assignment submission. And sometimes they don't allow me to upload an assignment. The dashboard with the paper clip icon is sometimes available and sometimes not.
I didn't have this issue in Oncourse. I understand that comments can be made in Crocodoc, but I like the options the comment feature in Word offers. How can I ensure that I am consistently able to upload a document in response to a student's assignment submission?
