I have an Android version of my app and integrated FAN into my Application. It worked for some months but now it's displaying "NO FILL"
Error Domain=com.facebook.ads.sdk Code=**1001 "No fill"**
UserInfo={NSLocalizedDescription=**No fill**,
FBAdErrorDetailKey={ msg = "**No fill**"}}
And no FAN ad is shown. If I put a testing ID then it's displaying, but only on my device, not for another device.
How to resolve this problem "No Fill"?
compile 'com.facebook.android:audience-network-sdk:4.+'
Mentioned in build.gradle I've seen many questions regarding this but unable to find an answer.
I've already seen below links:
