Hi Sir,
We update our ad implementation to "Google Mobile Ads SDK 6.12.0" (use we DFP account), and i notice a display difference between interstitial ad on a device running iOS 7 and iOS 8.
On iOS 7 (iphone 4,5, ...) ad is correctly display and on iOS 8 (iPhone 5, 6, ...) it's seems on top and left border a margin is added so the interstitial is not correctly display and is crop
I imagine may be we can resolve this issue with custom CSS on the ad template but i haven't yet test it and i want inform yout about this display difference between iOS version.
Complementary information :
issue reproduce with google test tag : /6253334/dfp_example_ad/interstitial
Best regards
