I was working on a project and after saving it, it would come up as a hexagon with a black X. after redoing the project 5 times, the project froze while trying to save. I restarted my ipad and went back into ps touch, every project I've ever worked on is gone. No sure if I had the cloud turned on but there's nothing out there either. So I just tried to do another project to test it out and after saving it, nothing shows up in my projects. Not even the training ones like the blue stop sign. Any clue how or if I can retrieve my projects??
As far as the project that crashed goes, it may be corrupt. There may be no getting it back.
I'm puzzled as to your other projects, though. Do you have enough free storage space on your iPad?
