C# unity中的Firebase身份验证登录始终返回新用户

我尝试使用身份验证登录Unity中的firebase用户帐户，但我的问题是，如果我使用了错误的信用或正确的登录信用（相同的结果），我会返回一个新用户（未验证电子邮件…）。是否有任何方法可以修复它，并获得正确的用户或无用户，如果用户不存在。下面的代码是我用于身份验证的所有代码。为了防止有人误解新用户，不会创建新用户。我获得的信息与新帐户的信息类似

我希望有人能帮助我。提前谢谢

            using Firebase;
            using Firebase.Database;
            using Firebase.Unity.Editor;
            using Firebase.Auth;
            .
            .
            .
            FirebaseApp app = FirebaseApp.DefaultInstance;
            app.SetEditorDatabaseUrl("this is my database url");
            if (app.Options.DatabaseUrl != null) 
                app.SetEditorDatabaseUrl(app.Options.DatabaseUrl);
            Firebase.Auth.FirebaseAuth auth = FirebaseAuth.GetAuth(app);
            auth.SignOut();//I don't know if this line is required, I just have it since I thought maybe the user is cached
            auth.SignInWithEmailAndPasswordAsync("example@gmail.com", "any password").ContinueWith(task => {
                if (task.IsCanceled)
                {
                    Debug.LogError("Task was canceled.");
                    return;
                }
                if (task.IsFaulted)
                {
                    Debug.LogError("Task encountered an error: " + task.Exception);
                    return;
                }
                if (task.IsCompleted)
                {
                    //This case is true
                    Debug.Log("Task Completed");
                }
                Firebase.Auth.FirebaseUser newUser = task.Result;
                Debug.LogFormat("User signed in successfully: {0} ({1})",
                    newUser.DisplayName, newUser.UserId);
                Debug.Log(FirebaseApp.DefaultInstance.GetEditorAuthUserId());//This is always the email adress
                Debug.Log(auth.CurrentUser.IsEmailVerified);//This is always false even if I use the correct password and email adress and verified it
            });

确保您的google-services.json文件位于项目中。这就是我遇到的问题，从firebase控制台下载json文件后，问题得到了解决
