title: Expo Snack: _firebase.default.firestore is not a function
body: <p>I made a service in my React Native Expo Snack app that handles the instantiation of different firebase services. Somehow, Snack isn't able to find firestore, as it says "_firebase.default.firestore is not a function". The code used is shows below:</p>
  
  <pre><code>import firebase, { firestore } from 'firebase';
  
  const config = { ... // Deleted, assume the config is correct }
  
  export const FirebaseApp = !firebase.apps.length ? firebase.initializeApp(config) : firebase.app();
  
  export const Firestore = firebase.firestore();
  
  export const Auth = firebase.auth();
  </code></pre>
  
  <p>Can somebody confirm this should work in Snack? Why doesn't it recognize firestore() as a function?</p>
