Ad viewability

[RonanDrouglazet]

Hi,

At this moment, the API window.context.observeIntersection fires callback only on scroll end (but really at the end !)
So we can't get changes with accurately. Actually, the viewability does not fires a lot.. sometime never fire (even if the scroll is ended)

e.g:

• user never stops scrolling and pass through our ad, we never receive the notification from viewability
• user keeps his finger on screen (scroll not release)

Would it be possible to fire viewability callback more often ? Like onscroll event ?

Thanks !

Thanks for the report!
I'll take a look. We will definitely throttle it, but we do want to send event during scrolling.
