Since the ad returns an overlay in our
VSI tool, your issue leans towards being more implementation specific.
In your
implementation, when you click on the video to play the player itself resizes. The new size of the player is too small to display your overlay ad. I believe you are running into the same issue that we've experienced in the
past, where the overlay ad content could not be displayed since creative dimensions do not align with the display area. Please let us know if this clarifies things.
