grey circle with an exclamation point

[AC Question]

I have a grey circle with exclamation point in the top right corner of my sms message app icon on my home screen. What does this mean? It also appears on my phone app icon on my home screen as well. I thought it was a failed sent message or failed phone call but that doesn't seem to be the issue.

Mine too! Ever find the answer? I think it is my launcher.
