Firebase AdMob间隙性ad仅显示一次反应

当我第一次点击按钮时，广告就会显示出来。但当我再次点击按钮时，它会给我一个错误

错误：firebase.admob.interstitalad.show请求的填隙Ad尚未加载，无法显示

我怎样才能解决这个问题？我想在每次点击按钮时显示一则广告

import { InterstitialAd, AdEventType, TestIds } from '@react-native-firebase/admob';

const adUnitId = __DEV__ ? TestIds.INTERSTITIAL : 'ca-app-pub-xxxxxxxxxxxxx/yyyyyyyyyyyyyy';

const interstitial = InterstitialAd.createForAdRequest(adUnitId, {
  requestNonPersonalizedAdsOnly: true,
  keywords: ['fashion', 'clothing'],
});

function App() {
  const [loaded, setLoaded] = useState(false);

  useEffect(() => {
    const eventListener = interstitial.onAdEvent(type => {
      if (type === AdEventType.LOADED) {
        setLoaded(true);
      }
    });

    // Start loading the interstitial straight away
    interstitial.load();

    // Unsubscribe from events on unmount
    return () => {
      eventListener();
    };
  }, []);

  // No advert ready to show yet
  if (!loaded) {
    return null;
  }

  return (
    <Button
      title="Show Interstitial"
      onPress={() => {
        interstitial.show();
      }}
    />
  );
}

这实际上是生产代码的一个片段-请欣赏
