擦除OAuth2 Playground中我所有的Google Play成就并不能消除我的成就

Question

如果我在游戏中解锁某个成就，然后重置，在为我的用户运行OAuth流程后，发布到https://www.googleapis.com/games/v1management/achievements/reset，我会收到正确的回复，

{
  "kind": "gamesManagement#achievementResetAllResponse", 
  "results": [
    {
      "definitionId": "CgkIh9rSofwUEAIQAQ", 
      "kind": "gamesManagement#achievementResetResponse", 
      "updateOccurred": true, 
      "currentState": "REVEALED"
    }
  ]
}

如果我再次发布到https://www.googleapis.com/games/v1management/achievements/reset，我会再次获得成功的空列表响应，如预期的那样，

{
"kind": "gamesManagement#achievementResetAllResponse", 
"results": []
}

但是当我回到游戏中，检查我的成就时，它仍然表明我有这个成就。无论我是否退出，登录，重新启动应用程序，没有任何区别，我仍然有这个成就，

即使我发布了完整重置https://www.googleapis.com/games/v1management/achievements/resetAllForAllPlayers，我也获得了成功，没有身体反应，
