AppleSignIn (with Firebase & Expo) working locally but not on standalone

Question

I implemented the signinWithApple button on my Expo app, and it's working perfectly locally when i use the host.exp.Exponent on Services ID in Firebase authentification tab for Apple Sign in.

But when I create a standalone app, and I test it with TestFlight, it doesn't work anymore whether I use host.exp.Exponent, nothing, or my specific app service ID on Services ID.

What am I missing here?

MY CODE :

handleApple = async () => {
    const csrf = Math.random().toString(36).substring(2, 15);
    const nonce = Math.random().toString(36).substring(2, 10);

    try {
      const appleCredential = await AppleAuthentication.signInAsync({
        requestedScopes: [
          AppleAuthentication.AppleAuthenticationScope.FULL_NAME,
          AppleAuthentication.AppleAuthenticationScope.EMAIL
        ],
        state: csrf,
        nonce: nonce
      });

      const {
        identityToken,

        fullName,
        email
      } = appleCredential;

      if (identityToken) {
        // login with credential
          const provider = new firebase.auth.OAuthProvider("apple.com");
          const credential = provider.credential({
            idToken: identityToken,
            rawNonce: nonce,

          });

          await firebase.auth().signInWithCredential(credential).then(user => {
          ...

EDIT :

I managed to make it work by using my bundle identifier (which is also my app id) on the Service ID field in firebase.

Error code :

Error: The audience in ID Token [##.app-videos] does not match the expected audience ##.signin.

But now the sign in with Apple on my website breaks. I manage to make it work when I change the Service Id field to my specific app service ID (found in Identifiers > Services IDs).

So i'm stuck with an app that requires something and a website that requires an other. Why is that?

Should I do something specific when I rebuild my app so that the changes that I made to mu identifiers are taken into account? I'm using this, is it not enough?

expo build:ios --clear-provisioning-profile

I had the same problem and should solve it in the following way.

You must re-create GoogleService-info.plist in the Firebase console with the same bundleId as in the project in Xcode.
