我无法使用亚马逊测试应用程序"package.com.aamazon.sample.institialad；"接收任何测试广告。我已经根据本指南实施了亚马逊移动广告：https://developer.amazon.com/public/apis/earn/mobile-ads/docs/quick-start
亚马逊10天前通知我，我的税务身份已得到验证。
这是我的Logcat日志：
AdRegistration: Debug logging has been enabled.
AdRegistration: Amazon Mobile Ads API Version: 5.9.0

我做错了什么？
感谢
NO_FILL表示当前没有可显示的广告。您可以尝试VPN&选择美国国家检查广告是否有效。你使用的是旧的sdk新版本可用，它是amazon-ads-6.0.0.jar
