Hello,
When I’m trying to show adMob interstitial ads, they are delayed about 5 seconds after using ads.show().
This is not so good, because these ads are not show instantly when user making actions such as button touch.
As I see, this can be resolved, invoking native interstitial.isReady() SDK function, but this is probably not possible in current Corona AdMob implementation…
Here is more about this:
