@Jimmyjoe123: It should still be possible to disable Do not disturb before it is scheduled to switch off, either via the Quick Panel, or by heading to Settings > Notifications > Do not disturb > Toggle it off.
If this isn't the case, then please can you confirm which option you have selected under 'For how long?' - 1. Until I turn it off, 2. A set number of hours or 3. Ask every time?
