iMessage "Message Failed to Send" but it did. . . .
For the past 3 days, when I try to send an iMessage, I get a notification saying "Message Failed to Send" yet the message did go thru. So, every time I send a message, I get this annoying notification back, but all my texts are going thru. I have a 5 with the latest update and I'm on AT&T. I've tried turning iMessage off and then on, restarting the phone, signing out of iMessage and back in, no luck. My husband, sister, mother and a friend are all having the same problem. Any ideas?
iPhone 5, iOS 7.0.3
