UPDATE: The plot thickens. I changed my channel name and it is suddenly working (which means it wasn\'t a problem with my push service, since I\'m getting the same HTTP response
are you getting the URL from each device? you need to get a URL from the push notification sevice for each device everytime your device connects,
when it does you need to find a way of retrieving the url from each client,
once you do that and your still not receiving push notifications then I would write to microsoft to see if they can see anything to do with the push notifications
