Work suddenly gone and previous versions won’t load
I have over a month of work saved on one illustrator file on my iPad which has been saving and opening fine until now. I have opened the file today and half of my work has gone. Most of the work that's gone are images/photos. It's a large file so I understand that it takes longer to load but I have tried to revert to an older version but that hasn't worked either. Any help would be greatly appreciated. Thank you.
