DND Issues

[Smaed]

Hi, can someone tell me why my Do Not Disturb doesn't work anymore? 

I have always had a schedule set for DND and it's always worked. Now, the schedule is ignored and I get notifications from texts, calls and anything else that comes through. I end up having to put my phone on silent. 

Any help is appreciated.

Do you get the sound still? Or no sound but still pop up? Cause the pop up won't go away, only the sound will. What phone do you have?
