  There are few moments in game development more frustrating than a successful build that fails to perform. You spend hours integrating Unity Ads, testing the reward logic, and verifying the placement in the Editor. Everything works flawlessly. Then you push to an Android device. The build runs, the game plays, but when you tap the "Watch Ad" button—nothing happens. No video, no error popup, just silence. If this scenario sounds familiar, you are likely a victim of aggressive code stripping or improper initialization sequencing. This guide moves beyond generic advice to fix the specific conflict between the Unity Ads SDK and the Android build pipeline (ProGuard/R8). The Root Cause: The "Silent Stripper" (ProGuard/R8) To understand why this breaks, you must understand how Unity compiles an Android application (APK/AAB). When you build for the Editor, Unity runs the Mono backend. It includes almost everything, ensuring maximum compatibility for debugging. However, whe...

  Receiving a policy violation notification from Google Play Console regarding "Invalid Privacy Policy" or "Missing CMP" is a critical blocker for mobile publishers. Google now strictly enforces the use of a certified Consent Management Platform (CMP) compatible with TCF v2.2. If you initialize Unity Ads (or any ad network) before resolving the user's consent status via Google's User Messaging Platform (UMP), you are technically tracking users without permission. This leads to app rejections and potential account bans. This guide details a robust, architectural approach to strictly order your initialization logic in C#, ensuring UMP resolves fully before Unity Ads ever touches the network. The Root Cause: Race Conditions in Initialization The core issue stems from the asynchronous nature of Unity's  Start()  lifecycle and SDK initializations. In a standard implementation, developers often place  Advertisement.Initialize()  and  MobileAds.Initialize()  ...
