[Mobile] App keeps crashing

Happens when I'm working with layers. One of the things I use Express for is to place tattoos on a model. I'll erase the background of the tattoo image (there's no background but I have to do that in order to erase parts of it) Once I zoom in to the image to edit or restore it crashes. Sometimes the app goes blank and all I see is the layers I added on my image. But the image is gone. There's no warning or alerts. 
when I restart the app it picks up right before I started the work on that image. Previous work, fortunately, has been saved.  
I can't record it because it's not something that I can predict will happen. Just happens more often lately. 

Me too. To the point it's useless.
