I have a mobile game in Unity 2022.3.62f3 targeting Android. In a debug build every AdMob test ad appears, yet the moment I switch to a release build the ads disappear and Gradle occasionally complains about Google-play-services / Firebase version clashes. Your task is to trace and fix the underlying dependency conflict, adjust any Gradle templates or External Dependency Resolver settings, and hand back a project that produces a clean release build (.aab) with ads reliably showing on a physical device. Key facts • Engine: Unity 2022.3.62f3 • Ad network: Google Mobile Ads SDK • Current symptom: Ads not displaying in release, sporadic Gradle build errors • Timeline: ASAP Deliverable – Updated Unity project that builds in both debug and release without errors – Banner, interstitial and rewarded test ads loading in release mode – Brief change log so I can replicate the fix on future versions Acceptance criteria 1. Gradle completes successfully with no version-collision warnings. 2. Test ads appear in release on my device. 3. Google Play pre-launch report shows no new compliance issues. I can supply the project via GitHub or zip and will test the final build immediately after your update.
