Hi, Maryann. The iPad app is slow slow slow and --on my iPad right now-- you cannot swipe to advance to the next student. This is very typical of Canvas / Instructure: a good idea that is implemented poorly, stops working unexpectedly, and is generally poorly thought out. I describe Canvas on both a browser and on the app as "passive aggressive" --they make core functionalities so difficult to use that it feels like it simply must be intentional. Nobody would design such a frustrating user experience across the product by accident. Use it if you want to but I will tell you that my experience w/ iPad grading using the Teacher App has been enormously frustrating. I really wish we used a competitor.
