Not seen much coverage of this issue I'm having so wondering if it's just me!? Notifications for native apps seem to be working OK it's third party apps which I'm having problems with, in particular erratic app badge notifications. I'll often get the banner and/or notification centre one but the badge will not display despite being enabled in notification settings. Is it worth trying a complete reset? Set up as new iPhone? Or is this a known issue with ios 6?
