Regarding turn-based games such as Words with Friends, Scramble with Friends, etc -- I would say that at least 9 times out of 10, Notification Center still shows that I have a turn waiting even after I've already taken my turn. I'm having to go into Notification Center and clear the notification manually almost every single time and it's frustrating. Theoretically, the notification should simply disappear after you've taken your turn. I thought it may be an issue with Notification Center wanting you to access the game through Notification Center, rather than just opening the app - but I'm still having the issue, regardless. Then, there's times I have the opposite problem - I have a turn waiting for me on a game and it's not in Notification Center at all! This issue, for me anyway, only seems to be an issue with games. E-mails, texts, reminders, etc, are never an issue - they always disappear after they're acknowledged. Is this a problem with Notification Center, or a problem with the games? This has been an issue for me ever since Notification Center was introduced.
