Redux-persist is returning initial State instead of persisting

I have added redux-persist in my code and it isn't persisting the state, instead I am always getting the initial state.

Here's the code of my root-reducer

import { combineReducers } from "redux";
import { persistReducer } from "redux-persist";
import storage from "redux-persist/lib/storage";
import userReducer from "./Users/user-reducer";
import cartReducer from "./Cart/cart-reducer";

const persistConfig = {
  key: "root",
  storage,
  whitelist: ["cart"],
};
const rootReducer = combineReducers({
  user: userReducer,
  cart: cartReducer,
});
export default persistReducer(persistConfig, rootReducer);

and this is my store.js file

import { createStore, applyMiddleware } from "redux";
import logger from "redux-logger";
import rootReducer from "./root-reducer";
import { persistStore } from "redux-persist";

const middlewares = [logger];
export const store = createStore(rootReducer, applyMiddleware(...middlewares));
export const persistor = persistStore(store);

Here's my index.js file

import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import App from "./App";
import { BrowserRouter } from "react-router-dom";
import { Provider } from "react-redux";
import { store, persistor } from "./redux/Store";
import { PersistGate } from "redux-persist/integration/react";
ReactDOM.render(
  <React.StrictMode>
    <Provider store={store}>
      <BrowserRouter>
        <PersistGate persistor={persistor}>
          <App />
        </PersistGate>
      </BrowserRouter>
    </Provider>
  </React.StrictMode>,
  document.getElementById("root")
);

Whenever I am refreshing my page with the initial state, I am getting rehydrated: true but after firing some action I am getting rehydrated: false.
