Photoshop for iPad crashing when zooming in pictures

Hey guys, been having a newly occurred issue over the last couple days. The Photoshop app on on my iPad keeps crashing everytime I try to zoom in to pictures. At other times, green blocks would appear, but if I keep zooming in, I would arrive at point where things are fine, unless I zoom out accidentally (then it crashes). Anyone experiencing the same issue? What's the fix?
