Note

Starting April 1, 2026, apps that monetize with Unity Ads through direct integration through the Advertisement Legacy Package might see reduced ad performance. To avoid reduction in performance, switch to integrating Unity Ads as a bidder.The Unity Ads network will continue to support and provide fill for all apps using direct integration. However, to maximize revenue and performance, the recommended best practice is to install the Ads Mediation package for LevelPlay, Unity's ad mediation platform.
