Is anyone else having trouble with the DND feature? I don't know if just still has kinks in iOS 7 or if I'm not doing something right. But whenever I turn it on, I don't get any notifications from anyone and I have it set to get alerts from favorites. I looked at my phone later and had a ton of missed texts. Maybe I just shouldn't use it in the meantime, but I was wondering if anyone else has this issue with DND.
