we've integrated Facebook Audience Network in our Android and iOS apps a few days ago. We're using AdMob Open Bidding mediation.
Technically speaking everything seems to be ok, the SDK is initializing as expected and the AdMob adapter has been integrated correctly.
However, right now Facebook is bidding on a very small percentage of our impressions (less than 5%), and the main reason seems to be the following according to the facebook dashboard: "no facebook profile found".
We were not expecting 100% of our users to have a facebook profile, but at least 50% let's say, 20-30% in the worst case. So there's clearly something here that isn't working as expected and that we're missing.
We've contacted their support and they told us that the users of our apps are required to login via Facebook in order for Audience Network to work, which sounds a little strange, since this is not mentioned anywhere in the official documentation. Also, we thought the advertising ID (IDFA on iOS) was more than enough to identify a user and track him across different apps.
So we were wondering: has anyone of you guys ever integrated Facebook Audience Network over AdMob (perhaps via Open Bidding)? If so, as far as you know, is Facebook Login really required?
