I'm trying to use fb audience network to show interstitials in my game.
On Android it works fine, but on iOS when I try to load an ad I always get the following event:
response: No fill - Error Code 1001
According to Facebook, this could occur because:
1. The person testing has not logged into the native Facebook app on their mobile device
2. The person testing has enabled "Limit Ad Tracking" (iOS only) or has selected "Opt out of interest-based ads" (Android only) in their device settings.
3. We don't have ad inventory to show for that person
I ruled out 1+2, and the 3rd is unlikely -
I have tried it with several phones (in England and Israel), so there should be ads available.
Also, for the same facebook user I get ads in Android, so it looks like an issue with the plugin itself.
Can someone take a look?
