codah Thanks, thats actually helped. I've never used preload interstitial before as i didn't notice a difference, but i've noticed that if i set preload interstitial on the layout before i want my ads to show, it works without much delay.
I've got just a few more thing i need help with -
1. After using preload interstitial, the interstitial ads don't show up all the time, only around 3 out of 5 times. It used to show up all the time before using preload, albiet it would be delayed as mentioned previously.
2. When using preload banner, for some reason when the banner loads it's a smart banner, even though the size of my banner that i selected was 'banner'. After a while it does change to the correct size but is there a reason why it switches to smart banner first?
3. Last thing is, does the preload action usually affect the gameplay if it's used at the start of that layout? I have a interstitial and banner ad shown on my game over screen, and when i use the preload interstitial and banner ads, the ads show up how i want which is great. But i've noticed that my game does lag when using the preload action on the gameplay layout, which wasn't the case before using this.
Thanks
