android admob google-play-services interstitial video ads and dismissal

Question

I received a user review that describes "having to sit through a video ad".

I thought all interstitial ads were easy to dismiss via either the device back button or the included [x] button...

Are there video ads that force a user to watch a portion / the whole video before being "dismissable"?

If so, is there a way of preventing such ads from being in the "ad lineup"?

Answer 1

I have never come across an ad that wasn't cancelable.
