When I got the iPhone 5s and transferred my 4s backup to it, it seems I have lost many of my notification alerts (like from AP Mobile and Dark Sky). I have not systematically verified it, but it seems that the only alerts I still get are from new applications (like Omnifocus 2) or from Apple applications that were updated in iOS 7 (like Mail). The old notifications are still *on* in the System Settings of Notifications, and I even tried to delete the AP Mobile app, restart the iPhone 5s, then download it again from the iTunes Store, but it didn't work - I still don't get notifications from them on my iPhone 5s. I know that I am missing them because they still show up on my iPad (which is still my old iPad 3 but has been updated to iOS 7). Any suggestions?
