Additional Meta AudienceNetwork steps

Meta Data Processing Options for Users in California

For information about how to implement Meta Limited Data Use flag in California, visit Meta developer documentation.
CAS provide an alternative way of pass FBAdSettings.setDataProcessingOptions flags using MediationExtras.facebookDataProcessing with values:

• "" to explicitly not enable Limited Data Use (LDU) mode
• "LDU" to enable LDU mode using geolocation
• "LDU_1_1000" to enable LDU for users and specify user geography

Define LDU flag in CAS manager builder before initialization:

CAS.MobileAds.BuildManager()
    .WithMediationExtras(MediationExtras.facebookDataProcessing, LDU)
    ... //Other parameters
    .Initialize();

iOS Advertising Tracking Enabled for Audience Network

Implement the setAdvertiserTrackingEnabled flag, irrespective of the use of mediation, to inform Meta whether to use the data to deliver personalized ads.
CAS provide an alternative way of pass FBAdSettings.setAdvertiserTrackingEnabled flags using MediationExtras.facebookAdvertiserTracking.

• Value "1" flag to inform Audience Network to use the data to deliver personalized ads in line with your own legal obligations, platform terms, and commitments you’ve made to your users.
• Value "0" flag to inform Audience Network to not be able to deliver personalized ads.

CAS.ATTrackingStatus.Request((status) => {
  CAS.MobileAds.BuildManager()
    .WithMediationExtras(MediationExtras.facebookAdvertiserTracking, isTrack ? "1" : "0")
    ... //Other parameters
    .Initialize();
});

⭐ This functionality is for iOS only and will not have any effect on Android.

Facebook SDK Migration

If your project uses the Facebook Unity SDK, you must be on version 11.0 or later for the MAX Facebook Audience Network adapter to function. To migrate from an older version of Facebook Unity SDK, delete the Assets/FacebookSDK directory, then download and re-import the latest version here.❕

Network security configuration

The Audience Network Android SDK use 127.0.0.1 (localhost) as a caching proxy to cache media files in the SDK. Since Android 9, cleartext traffic (unencrypted HTTP) will be blocked by default, which will affect the functionality of media caching of the SDK and could affect user experience and ads revenue.
