Wanted to give people an update for those of you trying to use BB10 Core Native Ads and have failed to get them working. You MUST set your ZoneID Width and Height values to what you specified in your game for Live Ads to work! 320x50 Ads are working, not sure about other sizes. I have published a simple free pong app to confirm this is working called "Cosmic Pong" you can download to see Ads are working. In the BB10 Ad Web console I get fill-rate and clicks register on the BB10 server. Only thing I notice is only one Ad gets filled/presented to the user currently. May be the lack of BB10 advertisers idk. I documented this more here: http://www.reign-studios.net/docs/unity-plugin/blackberry-10/ Scroll to the bottom of the page. Anyway hope this helps others.
