Save Button Doesnt Work?

I love Sketch Club. I love the new update. I love to draw. Unfortunately with the new update, when I hit the save button and close out of the app completely, then come back in later to work on my drawing again, it is all gone. All the hard work I put into the same picture over and over again is gone every time I get back on, whether I hit save or not. It always says that it saved, but I never see any result of it. I would give this app 5 stars if it wasnt for that issue, but since it has proved to be a problem every single time no matter what I do to save it, I am only giving it 3 stars. I dont have the time to work on an entire picture all at once, but if I want to finish a drawing that is what I have to do. Again, I love everything else about this app except for this new problem I have come across with the new update.
