I tried showing both Banner Ad and Full Screen Ad(both on the Game Over Layer).

The 1^st Banner Ad shows up late and If the user clicks retry, I call the hideBannerAd(). So if the user clicks retry before the ad shows up, the ad is never seen.
If the user doesn’t click anything for a minute, the banner Ad shows up and the subsequent Ads are displayed without delay. So how do I display the first Ad instantly?

And, while trying the full screen Ad, I used the preLoadFullScreenAd() but still the FullScreen Ad is delayed. It shows up only when the user has clicked retry and the game has already started!

Solving either of the issues would be fine! :)
