Java 谷歌admob错误。当我使用我的ads单元ID时，不会显示广告，但测试ads单元ID工作正常

广告单元不工作测试广告确实会显示，但当我尝试使用我的广告单元id时，我会得到“无广告配置” 我已经实现了所有必要的配置和中介

这是我加载和显示广告的代码：

//Ads will load on click.
load_add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            rewardedAd = new RewardedAd(context, "ads unit_ID");
                rewardedAd.loadAd(new AdRequest.Builder().build()  ,

                        new RewardedAdLoadCallback(){
                    @Override
                    public void onRewardedAdFailedToLoad(LoadAdError loadAdError) {
                        super.onRewardedAdFailedToLoad(loadAdError);
                        Log.d("CRAP" , loadAdError.getMessage());
                        // i get not ads config error when i log this message. 
                    }
                    @Override
                    public void onRewardedAdLoaded() {
                        super.onRewardedAdLoaded();
                        Log.d("CRAP" , "Success");
                        if(rewardedAd.isLoaded()){
                            Log.d("CRAP" , "Ads Loaded");
                            rewardedAd.show(Credits.this , new RewardedAdCallback() {
                                @Override
                                  public void onRewardedAdOpened() {
                                    // Ad opened.
                                }
                                @Override
                                public void onRewardedAdClosed() {
                                    // Ad closed.
                                }

                                @Override
                                public void onUserEarnedReward(@NonNull RewardItem reward) {
                                    // User earned reward.
                                }

                                @Override
                                public void onRewardedAdFailedToShow(AdError adError) {

                                }

                            });

                        }else {
                           // Ads did not load
                        }
                    }
                });



        }
    });
