android-AdMob奖励广告未展示

Question

我尝试在VPN上也未显示我的AdMob奖励视频，但它仅在美国或加拿大的VPN上显示，而在英国，荷兰或主要国家（乔治亚州）没有显示。这也是我的代码，我认为一切正确，对吗？ ：/

代码：

MobileAds.initialize(getApplicationContext(), "ca-app-pub-4280838209894831~8907955720");

    // Use an activity context to get the rewarded video instance.
    mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
    mRewardedVideoAd.setRewardedVideoAdListener(this);
    loadRewardedVideoAd();

    reward.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mRewardedVideoAd.show();
        }
    });

    // LoadScore
    SharedPreferences myScore = this.getSharedPreferences("MyScoresAmount", Context.MODE_PRIVATE);
    score = myScore.getInt("crystals", 0);

    txtScore.setText(String.valueOf(score));


}

@Override
public void onResume() {
    mRewardedVideoAd.resume(this);
    super.onResume();
}

@Override
public void onPause() {
    mRewardedVideoAd.pause(this);
    super.onPause();
}

@Override
public void onDestroy() {
    mRewardedVideoAd.destroy(this);
    super.onDestroy();
}

@Override
public void onRewarded(RewardItem reward) {
    Toast.makeText(this, "თქვენ მიიღეთ " + reward.getAmount() + " " + reward.getType() + "!", Toast.LENGTH_SHORT).show();
    // Reward the user.
    score += 1;
    txtScore.setText(String.valueOf(score));

    // Save Score
    SharedPreferences myScore = getSharedPreferences("MyScoresAmount", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = myScore.edit();
    editor.putInt("crystals", score);
    editor.commit();

}

private void loadRewardedVideoAd() {

        mRewardedVideoAd.loadAd("ca-app-pub-4280838209894831/6352587335",
                new AdRequest.Builder().build());


}

是欧盟禁令还是类似的禁令？
