我需要帮助Firebase for Unity。
当我在使用Google进行身份验证后尝试从数据库中编写（或读取）时，我得到Firebase Database error: Permission denied（虽然在Facebook上运行正常）但重新启动应用后，它让我可以读写，不再抛出错误。
它最近开始发生，因为它在一周前工作正常。我的规则也正确设置（它第二次工作，这不是问题。它也适用于Facebook）。
我正在使用FirebaseAuth.DefaultInstance.StateChanged，它甚至会在那里抛出错误。已填充FirebaseAuth.DefaultInstance.CurrentUser变量 。我认为认证流程没有任何问题，因为它第二次启动应用程序时工作（Firebase已经登录，我只是通过google重新验证并调用SignInWithCredentials方法）由于某种原因。
我应该在身份验证后添加某种延迟吗？或者是别的什么？我错过了更新吗？
我已经阅读了其他问题，但没有一个有效。
