ACS Production push notifications failing

Hi all, I recently submitted an iOS and Android app containing support for push notifications which worked when debugging on my devices using the development tab of the Appcelerator website. However now the apps have gone live every new iOS device ends up subscribing successfully to the development version, which is strange as it should be in the production tab. This is a minor problem however compared to that all the attempted push notifications fail with the message below:

I have tried sending on the channel 'Web Console' as suggested here : http://developer.appcelerator.com/question/154198/acs-push-notification-only-work-with-channel-web-portal which didn't help

This is the function being called

function registerForPush() {
    var osName = Ti.Platform.osname;
    var Cloud = require('ti.cloud');
    Cloud.debug = true;
 
    var deviceToken;
 
    function getDeviceTokeniPhone() {
        Titanium.Network.registerForPushNotifications({
            types : [Titanium.Network.NOTIFICATION_TYPE_ALERT, Titanium.Network.NOTIFICATION_TYPE_SOUND],
            success : function(e) {
                deviceToken = e.deviceToken;
                Ti.App.Properties.setString("device_token", deviceToken);
                defaultSubscribe();
            },
            error : function(e) {
                Ti.API.error("Error during iPhone push registration: " + JSON.stringify(e));
            },
            callback : function(e) {
                // called when a push notification is received.
                var data = e.data
                Titanium.Media.vibrate();
                alert(e.data.alert);
            }
        });
    }
 
    // Login with testing details
    function loginIphone(e) {
        Cloud.Users.login({
            login : 'defaultuser',
            password : 'defaultpassword'
        }, function(e) {
            if (e.success) {
                getDeviceTokeniPhone();
            } else {
                Ti.API.error('Error logging into iPhone ACS for push:\\n' + ((e.error && e.message) || JSON.stringify(e)));
            }
        });
    }
 
    // subscribe to push notifications on default channel 'alert'
    function defaultSubscribe(platform) {
        Ti.API.error(platform);
        Cloud.PushNotifications.subscribe({
            channel : 'alert',
            device_token : deviceToken,
            type : platform
        }, function(e) {
            if (e.success) {
                Ti.API.info('Subscribed for '+platform+' push notifications');
            } else {
                Ti.API.error('Error subscribing for ACS push:' + ((e.error && e.message) || JSON.stringify(e)));
            }
        });
    }
 
    loginIphone();
}

As far as I know, by following tutorials and implementing it the way other have, it should work.

Could it be something to do with the fact it is registering for development push notifications even though it must be signed with the production certificate from Apple as it is live in the App Store? Any help would be much appreciated thanks
