I should have done more testing.  This all started when I shared a story on Facebook for iOS.  The link opens in a facebook browser and the article still asks you to sign in.  If I open the article in Safari, it is does bypass the paywall fine.  For some reason the "facebook browser" does not bypass the paywall.  [the image attached is what it looks like when you open the link from facebook].  Its ok, I don't really car anymore; I was just trying to share a story relevant to a friend.  I thought maybe mobile_adv needed a special custom property.  I'm satisfied with the answers.
