Question about retargeting MOF. I noticed today that after creating a custom audience from ThruPlays on a TOF video, the audience was estimated to be relatively smaller than the results of my TOF campaign.Question about retargeting MOF. I noticed today that after creating a custom audience from ThruPlays on a TOF video, the audience was estimated to be relatively smaller than the results of my TOF campaign. After looking into it, Facebook says they don't include views from the Audience Network. If you can't include Audience Network viewers into your Custom Audiences, what's the point of running ads on that placement? Essentially there is a MASSIVE group of people I can't retarget now. Can someone help me understand this a little better?
