Our students have 32gb iPad Airs and are currently using iOS 7.1.1. We've had several students come in to the IT office over the last couple days saying that a project they had been working on in iMovie has disappeared. The alert notification that popped up says that the video they were using can no longer be found or the file name has been changed. When we try to search for it, the iPad can't find the file. We check in the camera roll and there are NO more photos OR videos in her camera roll even though the student insists she had a good amount of photos and videos in there. In addition, "Upload to iCloud" was turned on for iMovie as well as Photo Stream in her iCloud settings. So where did her iMovie project and other pictures and videos go? I tried accessing them via a Mac by opening the iCloud dashboard but no projects or photos and videos are showing up in there either. How can we avoid students loosing their school work in these apps?
