Fun and frustrating

This would be the best coloring app by far if only when the pic your coloring is zoomed in it would stay that way until you want it reduced. I zoom it in and after 2 strokes it goes back to its original small size. This happens every time with every coloring page!! Its so frustrating I am almost to the point of deleting the app. The only reason why I havent is because I purchase all the colors!! Please fix it!
Because of this glitch Im only giving it 1 star, if it were fixed Id give it 5 stars.
