Hello. I marked up papers for a class of mine on the Canvas app for iPad. I was very happy with the function. I was able to write directly on the papers and the marks showed up. I was able to save the corrections and enter a grade.
Well, you know where this is going... The papers had showed mark ups over the course of a week (on my iPad at least) and it seemed to be only and responsive. (Several late papers came in as I worked, for example.) Now there are no marks on the papers I graded. The numerical grades are still entered. I cannot even get the iPad app to open any of the papers now, including a few I did not grade. And the students cannot see the mark-ups from their end.
I spent a long time grading. Any advice on what I did wrong or how I can retrieve my marks would be welcome!
Thanks (and here's hopin'),
