c# - UnityAds はエディターでのみ機能します

Question

Unity でモバイル ゲームを作成しており、収益化のために UnityAds を使用する予定です。アセットストアから「Unity Monetization 3.1.0」パッケージをインポートしました。ユニティで実行すると、すべてが機能しているように見えますが、ビルドして Android フォンでテストしても何も起こりません。

これは私のコードです:

    private void Start()
    {
        Advertisement.Initialize(gameId);
        StartCoroutine(ShowBannerWhenReady());
    }

    private IEnumerator ShowBannerWhenReady()
    {
        while (!Advertisement.IsReady(bannerId)) yield return null;
        Advertisement.Banner.Show(bannerId);
    }
