Note
Starting April 1, 2026 applications that monetize with Unity Ads through direct integration via the Advertisement Legacy Package might see deterioration in Unity Ads network performance unless the integration is switched from direct to integration of Unity Ads as a bidder.The Unity Ads network will continue to maintain the Advertisement Legacy Package and provide fill on all applications with direct Unity Ads 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.
To ensure that you're using the latest version of Unity Ads, we recommend that you install the Advertisement Legacy package from the Unity Editor Package Manager.
  1. Open the Unity Editor, and go to Window > Package Manager.
  2. In the Package Manager window, ensure Unity Registry is selected as the Packages type.
  3. Navigate through the package list, find the Advertisement Legacy package, and then select the latest verified version.
  4. Select Install or Update.
If you can't find the the Advertisement Legacy package in the list, try searching for it:
  1. In the Package Manager, use the search bar and enter "Advertisement Legacy” or “Ads”.
  2. The package will appear in either of these locations:
  • All tab - listed as a package.
  • Services tab - listed under Monetization.
If the package still doesn't appear, add the Advertisement Legacy package by its name:
  1. In the Package Manager dropdown, select the plus button.
  2. Select “Add Package by Name”, then enter 
    com.unity.ads
    to search for it.
  3. Select the latest verified version and select Install or Update.
Note
Disabling domain reloading in Play Mode Options is not supported for the Unity Ads package.
If you created your project through the Unity Editor flow, you must also link it to a Unity Ads Monetization dashboard Project ID before it can access Unity Gaming Services. Refer to Configure a project for Unity Cloud. Next steps: To continue your integration, refer to the Initialize the SDK in Unity documentation.
