new app life cycle xamarin forms and iOS push notifications

Hello,
using the new app life cycle (xamarin forms 1.3) I can't receive notifications from apple APNs.
The registration works perfectly but the callback DidReceiveRemoteNotification is never called.
The notification is received by the device but I can't manage it in the app.
Switching in the old version method (using xamarin forms 1.3 but without the new app life cycle) everything works great.
Is it a bug?
