iMessage problems since 9/12

[/dev/toaster]

I have half of my devices running iOS 7 and half running iOS 6. I have a group chat with some friends, and when anyone sends a message to the chat. We get a warning saying it couldn't be delivered.

If I send a message from either version of iOS, I get this warning. However, my wife has iOS 6 only and doesn't have this problem.

Has anyone else experienced this ?

I haven't but I have noticed the past few days that iMessages are being marked as "delivered" for quite some time. Wonder if it's related.

I'm on iPhone 5 iOS 7 GM.
