Ad Banners on IOS issue - not hiding/closing

Greetings, I have a new game on the Apple App store… and it is serving Ad Mob ads:

https://itunes.apple.com/us/app/puppies-memory-match/id1443581420?mt=8

I have the same game in Google Play store. The Android works great - and it shows and HIDES banners depending on what screen/level you are on.

PROBLEM: The App store one, does not HIDE, or CLOSE the ad banner once Shown. So it appears on all screens. (over my graphics). I’ve tried Hide Ad Banner, and Force Close Ad Banner. These seem to do nothing.

Any ideas to what the trick is to hide an admob banner ad on ios once shown?? Thanks!!
