Why ads not appear in production version?

Expo Development Tools
1 
import { AdMobBanner, setTestDeviceIDAsync } from "expo-ads-admob";
const RequestScreen = ({ route, navigation }) => {
useEffect(() => {
    setTestDeviceIDAsync("EMULATOR");
 }, []);
return(
<View style={{ flex: 1 }}>
<AdMobBanner
            bannerSize="fullBanner"
            adUnitID="ca-app-pub-xxxxxxxxxxxxxxxxx/yyyyyyyyyyy"
            servePersonalizedAds
            onDidFailToReceiveAdWithError={(e) => console.log(e)}
          />
</View>
)
}

Hey @mohaned110, can you detail exactly what is happening on the production version? Are you receiving any errors in prod?

Also, can you let me know the relevant versions for your project? Lastly, how are you building the android binary?

Cheers,
