title: Admob ads cycling when the phone is locked
body: <p>I have made an app that has a banner ad at the bottom. The app will be used for the most part while the screen is locked. My question is will the banner ads on the screen continue to cycle through on the app when the phone is locked, and if so how do I prevent this from happening so my app does not get banned? </p>
  
  <p>Any Feedback is appreciated :)</p>
