Redux useSelector钩子不检索更新状态

Question

正在进行私有路由，如果用户未通过身份验证，但是useSelector()尚未更新，则需要重定向。我还使用redux-devtools

提供了我的状态的屏幕截图

App.js

  const App = () => {
   const dispatch = useDispatch();

  useEffect(() => {
    dispatch(loadUser());
  }, []);

  return (
    <Router>
      <Switch>
        <Route path='/' exact component={Home} />
        <Route path='/register' exact component={Register} />
        <Route path='/login' exact component={Login} />
        <PrivateRoute component={Dashboard} path='/dashboard' exact />
      </Switch>
    </Router>
  );
};

加载用户操作

const loadSuccess = (data) => {
  return {
    type: AUTH_SUCCESS,
    payload: data,
  };
};

const loadFailure = (errors) => {
  return {
    type: AUTH_FAILURE,
    payload: errors,
  };
};

export const loadUser = () => {
  return async (dispatch) => {
    try {
      const res = await axios.get('/users/current');
      dispatch(loadSuccess(res.data));
    } catch (error) {
      dispatch(loadFailure(error));
    }
  };
};

-编辑： authReducer.js

const initialState = {
  token: null,
  isAuth: false,
  loading: true,
  user: null,
  errors: [],
};

const authReducer = (state = initialState, action) => {
  switch (action.type) {
    case AUTH_SUCCESS:
      return {
        ...state,
        token: localStorage.getItem('token'),
        isAuth: true,
        loading: false,
        user: action.payload,
        errors: [],
      };
    case AUTH_FAILURE:
      return {
        ...state,
        token: localStorage.removeItem('token'),
        isAuth: false,
        loading: true,
        user: null,
        errors: action.payload,
      };
    default:
      return state;
  }
};

export default authReducer;

PrivateRoute.js

const PrivateRoute = ({ component: Component, ...rest }) => {
  const isAuth = useSelector((state) => state.authReducer.isAuth);
  console.log(isAuth);
  return (
    <Route
      {...rest}
      render={(props) =>
        isAuth ? <Component {...props} /> : <Redirect exact to='/' />
      }
    />
  );
};

export default PrivateRoute;

到目前为止，我相信操作已在主App.js文件中正确调度，并且状态正在更新，如下图所示：

但是console.log(isAuth);显示false。 知道这里有什么问题吗？
