Now this may not be a problem with the module but hopefully you'll be able to advise as to what it wrong.
I did have this working a couple of weeks ago but it seems to have stopped working now and I'm not sure where the problem lies. As far as I can tell my app code is correct and the device is registered. Also I'm not getting errors when sending the notification, but the device is not receiving any notification
Therefore I can only think maybe it is a problem with my app or a problem with the certificates. Any suggestions would be welcome as I'm a bit stuck.
