Galaxy S6 Edge Do Not Disturb Issue

[AC Question]

My alarm still goes off when using DND and the only exceptions are calls/messages from favorite contacts only. This started after the 7.0 upgrade. I've verified that the clock app is not set as a priority in the app notification section, which would override the DND setting.

Any thoughts?
