I need some clarification on one thing.
I created an app for a videoplayer. My issue is that my video plays while "Interstitials" or "App Open" ads are playing.
Does this violate the AdMob regulation or not?
I have searched for this information but could not find a result.

This is a violation of google ad policy:
