I have two devices (iPhone 4 and 5 with iOS 7) running the same app (Titanium SDK 3.2.2). Both devices successfully subscribes to the same push channel (Cloud.PushNotifications.subscribe() returns success = true). But when I tries to send a push notification using the Web Console only the iPhone 5 receives the push notification.
I have also tried to send a push notification from one device to the other with the same result: The iPhone 5 receives the notification, the iPhone 4 doesn't.
The iPhone 4 has received some (about 4 of 40) notifications, but when it happens, it's always after several minutes delay (the iPhone 5 receives the same notification immediately).
Is there any reason an iPhone 4 shouldn't receive all push notifications, and when it does it's after several minutes delay?
