My students have been submitting their assignments by using adobe acrobats app to write over the pdfs I have provided. They have been doing this for years now. I use the ipad to grade these because the interface is much more efficient that Schoology's pc/desktop interface. All of a sudden this week when I go to look at my students work. It appears for a split second and then disappears. I know I can have them take a screen shot a submit the image of thier work. But it is not as user friendly/efficient as a direct submit from AAR to Schoology. Any help would be much appreciated.
PDFs that students have used Adobe acrobat reader to submit to an assignment disappear!!!!!
