Firebase Auth使用电子邮件和密码登录需要3.52分钟

我已经使用Firebase Auth差不多一个月了，直到上周，Firebase Auth工作得又快又干净，但突然间只用了3。52分钟。我检查了每一行代码，到处搜索，仍然不能找到原因。

Java代码:

public class Login extends AppCompatActivity {
    private static final String PREFS_NAME = "preferences";
    private static final String PREFS_UNAME = "Username";
    private static final String PREFS_PASSWORD = "Password";
    private final String DefaultUNameVal="";
    private final String DefaultPasswordVal="";
    
    private usermodel uMod;
    private String Code,Name, UserN,Password,Type;
    private FirebaseFirestore db = FirebaseFirestore.getInstance();
    private CollectionReference SchoolColl = db.collection("School");
    private EditText Username,Pass;
    private Button LoginSubmit;
    private FirebaseAuth FsAuth;
    private CheckBox RememberMeBox;
    private String TAG="Datacheck";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        FsAuth = FirebaseAuth.getInstance();
        Username=findViewById(R.id.Username);
        Pass=findViewById(R.id.LoginPass);
        LoginSubmit=findViewById(R.id.Login);
        RememberMeBox=findViewById(R.id.RememberMe);
        loadPrefenreces();
        
        LoginSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(RememberMeBox.isChecked()){
                    savePreferences();
                    loginuser();
                }else {
                    resetPrefernces();
                    loginuser();
                }
            }
        });
    }
    private void resetPrefernces() {
        SharedPreferences settings = getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = settings.edit();
        UserN = "";
        Password = "";
        editor.putString(PREFS_UNAME,UserN);
        editor.putString(PREFS_PASSWORD,Password);
        editor.commit();
    }
    private void loadPrefenreces() {
        SharedPreferences settings = getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
        UserN = settings.getString(PREFS_UNAME,DefaultUNameVal);
        Password = settings.getString(PREFS_PASSWORD,DefaultPasswordVal);
        Username.setText(UserN);
        Pass.setText(Password);
        if(UserN != "" && Password != "") {
            RememberMeBox.setChecked(true);
        }
    }
    private void savePreferences() {
        SharedPreferences settings = getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = settings.edit();
        UserN = Username.getText().toString();
        Password = Pass.getText().toString();
        Log.d(TAG,String.format("Saving UserID (%s) & Password (%s)",UserN,Password));
        editor.putString(PREFS_UNAME,UserN);
        editor.putString(PREFS_PASSWORD,Password);
        editor.commit();
    }
    private void loginuser() {
        ProgressDialog Pd=new ProgressDialog(this);
        Pd.setCancelable(false);
        Pd.setMessage("Loading Student Data ...");
        Pd.show();
        UserN = "stpradhan@sparsh.org";
        Password = "stpradhan";
//        if(TextUtils.isEmpty(UserN)){

                        goToSchoolDashboard();
                        if(Pd.isShowing()){

                        }
                        finish();
                    }else{
                        Toast.makeText(Login.this, "User : "+UserN+" Login Unsuccessful.", Toast.LENGTH_SHORT).show();
                        if(Pd.isShowing()){
                            Pd.dismiss();
                        }
                    }

        });
    }
}

请帮助解决这个问题。
