[AdMob] Ads Adapter Fails After IronSource Integration

Under Audit

Published Tue, Mar 17

The Unity Ads adapter consistently fails to initialize via Google AdMob mediation, reporting an initialization state: 0, particularly after integrating IronSource.

Issue

 The GADMediationAdapterUnity fails to initialize when mediating through Google AdMob, consistently reporting an initialization state: 0. This issue appears to be directly linked to the creation of an IronSource account. Prior to the IronSource account creation, all existing project builds successfully initialized the Unity Ads adapter. Following the establishment of the IronSource account, all builds, including those previously functional, now report an initialization state: 0 for the adapter, and Unity impressions drop to zero.

Experimental Fixes
  • Verify AdMob mediation group configurations for both Unity Ads and IronSource to ensure no conflicting setups.
  • Check for potential SDK conflicts between the IronSource SDK and the AdMob mediation adapter for Unity Ads.
  • Confirm that the Unity Ads adapter and AdMob SDK versions are up to date and compatible with each other.
