Having trouble – Paint Color: Color by Number Review

I love this app but I have been having trouble since yesterday with it. Every time I click on a picture to color the whole page disappears and will not hardly come back. I deleted it and reinstalled it but that didn’t help. So I just deleted it again. Could you please fix that? I want to start coloring on the app again. Thank you
