    ```

2. Configure babel (`babel.config.js`)

     module.exports = function(api) {
       api.cache(true);
       return {
    -    presets: ['babel-preset-expo'],
    +    presets: ['expo-legacy-browser-support/babel'],
       };
     };
    ```

3. Add WebPack config (`webpack.config.js`)

    ```js
    module.exports = require('expo-legacy-browser-support/webpack')
    ```

4. Add polyfills (`package.json`)

    ```diff
     {
       "version": "0.0.0",
    -  "main": "node_modules/expo/AppEntry.js",
