Issue

Describe your issue here

When in Production environment AKA the app store, the FCM Token does not seem to be delivered to our application even when the user selects allow

import firebase                  from 'react-native-firebase';

functionalComponent() {
useEffect(() => {
        // The idea is once the user has logged in we will be able to check permissions
        //  Once we check permissions we will only upload tokens that aren't identical to the one
        //  The user already has within their DynamoDB Row
        if(cognitoUser.id) {
            checkPermissions();
        }
    }, [cognitoUser])

    async function checkPermissions() {
        const enabled = await firebase.messaging().hasPermission();
        if (enabled) {
            getToken();
        } else {
            requestPermission();
        }
    }

    async function getToken() {        
        try {
            let { token } = await registerTokenForUser(cognitoUser.fcmToken);

            // We only upload if the the FCM Token is different
            // Token return null so this function never runs.
            if (cognitoUser.fcmToken !== token) {
                await syncFCMToken(token);
            }
        }
        catch(error) {
            console.log(error);
        }
    }

    async function requestPermission() {
        try {
            await firebase.messaging().requestPermission();
            // User has authorised
            getToken();
        } catch (error) {
            // User has rejected permissions
        }
    }

// This function is used to grab the FCM Token and send it to sendbird then sends it back to the fn
export const registerTokenForUser = (token) => (
    new Promise(async (resolve, reject) => {
        const sb = SendBird.getInstance();

        try {
            if (Platform.OS === 'ios') {
                await getAPNSToken();
            }

            let FCMToken = await firebase.messaging().getToken();

            if (FCMToken !== token) {
                sb.registerGCMPushTokenForCurrentUser(FCMToken, function(result, err) {
                    if (err) return reject(err);

                    resolve({ result, token: FCMToken });
                });
            } else {
                resolve({ token: FCMToken });
            }
        } catch (err) {
            reject(err);
        }
    })
