frozen pen
the app has nice selections to color. i thought it would actually be like coloring, not touch and color. a few minutes into the app the pattern froze and I could not activate any color with my ipad pro. i have taken photos of an adult coloring book with my ipad and edited them to color with my pro pen. it was identical to coloring as if i had an ink marker in the actual book. please stop this from crashing. maybe you need a higher pixel resolution?
