“You are a winner” freezes app

Finally downloaded app after being prompted too every time I accessed Facebook on my iPad. In the two weeks since I started using the app I have gotten a “You are the winner of an Amazon gift card” pop up or something similar that has frozen the app. After twice deleting the app and reinstalling, I’m just going back to the web. Totally frustrating.
