Very Glitchy

I dont know if its just mine, but mine is very glitchy. Sometimes when I come into the app, some of my masks on my picture will go completely black. I try doing redo or undo and nothing works. I even tried to see if it was just the brightness or something. And it wasnt. You better fix this. Or else this app is just terrible. I would not recommend this app to anyone who doesnt like glitches.
