To enable the Ad review center, follow these steps:
- Sign in to your AdMob account at https://apps.admob.com.
- Click Blocking controls in the sidebar.
- Click Ad review center.
- Click Enable.
Your Ad review center is now enabled. You can start reviewing ads in about an hour.
At first, you'll only see ads that have shown in your apps since the Ad review center was enabled. Over the next day or two, more ads will appear on the Unreviewed tab of your Ad review center.
