The new facilities do not send the ID token

Hello everyone



I have a problem that I do not see where it may come from or if the problem is really mine, or the problem comes from some Apple update on the iphone devices. For a long time ago, the iphone devices that install an application of mine, do not send the ID token that allows you to send notifications to the application, even allowing in the installation the sending of notifications. The problem only exists in the new iphone and the updated iphone 6, since from the oldest it continues without problems the task of sending the ID token for sending push. Can someone tell me if this problem exists recently and how can I solve it?
