Note
If you’re upgrading or plan to upgrade to Android Gradle Plugin 9 / AGP 9 with 
isMinifyEnabled = true
, install the Unity Ads SDK 4.20.0.
If you’re using a Unity Ads SDK version earlier than 4.20.0 with Android Gradle Plugin 9 with 
isMinifyEnabled = true
, you must add the required keep rules to your own ProGuard configuration, otherwise Unity's diagnostic and operative events are silently dropped under R8.
