I successfuly managed to make push notifications (tile and toast) work on my device. But after a few days, it's not working anymore. However I get a good return status :

```
array(3) { ["X-SubscriptionStatus"]=> string(6) "Active" ["X-NotificationStatus"]=> string(8) "Received" ["X-DeviceConnectionStatus"]=> string(9) "Connected" } 

```

I tried to put the device in airplane mode, with no wifi, and I get 

```
array(3) { ["X-SubscriptionStatus"]=> string(6) "Active" ["X-NotificationStatus"]=> string(8) "Received" ["X-DeviceConnectionStatus"]=> string(16) "TempDisconnected" } 

```

So it's "kind of" working, right ? How come I don't see any notifications ? How can I debug further ?
