Ok, I hope I can explain this well enough that someone can help. I've had a student finish an assignment on Pages on an iPad. She then opened as a PDF in the Canvas App. We can see on the iPad on Canvas website that her new version is in Files. How do we get this to upload on an Assignment? With the iPad the only choices we see are from the Photo Library. This will be the same problem we need to figure out because many of my students start the work on Macs, save it to their Files, and then open it on iPads at home to finish. What is the upload process then to Assignments?
