I've noticed when I dismiss a notification on my iPad, it was immediately cleared from my iPhone. Although this was never consistent and I'm wondering if this notification syncing is only for apps that support it or what...? Apple didn't touch up about anything about notifications syncing. They didn't even talk about how notifications will only ring an alert on your most recently used device. Which only seems to work on the first party apps... again, is this something developers have to support? Is there anywhere that touches up on this!
