google-play - 在 OAuth2 Playground 中擦除我的所有 Google Play 成就并不会擦除我的成就

Question

如果我去解锁游戏中的成就，然后运行重置，在为我的用户运行 OAuth 流程后，发布到https://www.googleapis.com/games/v1management/achievements/reset，我会收到正确的响应，

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

如果我https://www.googleapis.com/games/v1management/achievements/reset再次发帖，我会再次收到成功的空列表响应，正如预期的那样，

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

但是当我回到游戏中，查看我的成就时，它仍然显示我有那个成就。不管我注销，登录，重启应用，都没有区别，我还有那个成就，

即使我发布完全重置，https://www.googleapis.com/games/v1management/achievements/resetAllForAllPlayers我也会成功，没有正文响应，
