What happened to a great app? – Bouncing Balls Review

I used to love this game, but now I keep getting pop up about winning an iPad and they want you to say ok to accept. The only way around this is to close and reopen the app. It is happening more frequently and is irritating. I have deleted app several times and downloaded again. No better. Also now most of the time app shuts down as soon as you open it. Or if it does open, it will close down suddenly while you are playing. Please fix this.
