i think it's been about a month now where even though all my settings are set to sounds on, there are no sounds during my facebook and instagram push notifications. Are any of you also frustrated at this? Is this a facebook/instagram problem or an ios 6 problem? I had sounds on my notifications before ios 6. Also, do any of you experience double notifications for instagram? like, when i open the app, old notifications jump up to my notification center so i see them twice. how can I turn that off?
