Having a youtube partner account, I need to programmaticly set the 'usage policy' of the monetization section.
When I update this field from the youtube interface for my video, I can see that the contentDetails/regionRestriction have been correctly updated.
But when I programmaticly call the update YouTube Data API v3, setting the contentDetails/regionRestriction seems to have no effect.
Which API should I call in order to programmaticly update this field (contentDetails/regionRestriction)?
