How to set a skippable preroll video ads?
We are using Google's DFP. When we configure Ad Skipping of our preroll video ads, we had a problem.
If we set client as 'vast', the preroll video ads can be skipped, but the ads didn't show up often, the fill rate is lower than 5%, most of the time we can only see the message "loading ads", but there is no ads displaying.
If we set client as 'googima', the preroll video ads display normally, but it cannot be skipped.
We need display a skippable preroll, Could you please help us to fix the issue? By the way, we use a third party ads tag.
