Illustration disappeared after Fresco froze

Hello!

I have been working on a drawing for a few hours with Fresco on my Ipad pro and the program froze while using the live brushes. Unable to do anything, I was able to click back to the home screen. Upon clicking back into my drawing I was devistated to see that the entire drawing had dissapeared, all the layers were empty and appearing blank. The drawing isn't in the deleted folder, it's still there with all of my layers but all of the work is missing. I'm hoping you can help me get the drawing back, as It was hours of work lost in a matter of three seconds... I've already reported the bug through the app, but I'm hoping I can find more immediate help here. 

Thanks for your time and help, 

Carmine
