Hello, well as many as you know today we got a new update of the developer preview, after i updated, i hard reseted, and when i installed whatsapp it now says that it's not compatible with the notifications of my system, and also it doesn't appear on the notification center, also twitter, facebook, and facebook messenger do not appear in the notifications center and i can't recive notifications,wpcentral, only text messages, phone calls, emaul and store, but not anything else, not even wpcentral app appears on the notification centers, please this is diving me crazy, i hard reseted the phone again and it didn't work, i think because i read on wpcentral that todays updated changed some apis.
