I'm an instructor who was just putting the finishing touches on a new rubric for a Canvas assignment. Then I clicked the assignment's "edit" button to check on something, but when I went back to the assignment page again using my browser's back button my rubric had disappeared. Normally Canvas warns me if I'm trying to navigate off an unsaved page when creating assignments, discussion post prompts, etc. Why is there no warning about the rubric not being saved? I didn't realize I had to hit "Create Rubric" to save it, thought there was some kind of autosaving happening. Has this happened to others? Is there an obvious way I can go and recapture the rubric I was making earlier?
