UPDATE ON App not working – Color4u: Adult Coloring Book Review

Update,,changing my rating the way it was before 5 **** I love this app ,for some reason it just quit working, well the fixed it for me. Thank you for getting back to me so fast. This app was working fine and now when I try to use it, It just kicks me out, can’t even open it up anymore. Have no idea except you said there was an update, I would assume that is why I cannot use it anymore, is there anyone who can help me get it back. Or tell me what happened. Thanks
