reactで画面遷移が出来ない

Question

reactの画面遷移を確認したく簡単なサンプルを動かしてみたのですが、画面遷移してもコンポーネントが表示されなく悩んでおります。

ネットのサンプル等はRoutesで挟んでない記述でしたが、下記エラーのためRoutesを追加しました。

A <Route> is only ever to be used as the child of <Routes> element, never rendered directly.

エラーは出なくなりましたが、今度はurlに該当するコンポーネントが空という警告が出て表示が動作しません。

index.tsx:25 Matched leaf route at location "/" does not have an element. This means it will render an <Outlet /> with a null value by default resulting in an "empty" page.

~/src/App.js

import React, {Component} from 'react';
import { BrowserRouter, Route, Routes, Link } from 'react-router-dom';

const App = () => (
  <BrowserRouter>
    <h1>Test Page</h1>
    <ul>
      <li>
        <Link to="/">top</Link>
      </li>
      <li>
        <Link to="/About">About</Link>
      </li>
    </ul>
    <Routes>
      <Route exact path="/" component={Home} />
      <Route path="/About" component={About} />
    </Routes>
  </BrowserRouter>
);

const Home = () => {
  return(
    <h1>Home</h1>
  );
}

const About = ()  => {
  return(
    <h1>About</h1>
  );
}

export default App;

package.json

  "name": "sampla-page",

      "not dead",

    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "react-router": "^6.2.1",
    "react-router-dom": "^6.2.1"
  }
}

ご教授頂ければ幸いです。

エラーがApp.jsではなくindex.tsxから発生してるところは気になりますね。
index.tsxの中身も追加お願いできますか？
