We are absolutely aware, we don't like the "Do Not Disturb" function. It automatically comes back on in the morning and you can't set a timer. This is in response to our dislike of the DND switch.
There's an option to set the time you want it to remain on. You can set it throughout the night just fine and it won't come on in the morning.
> you can't set a timer
I can tell it to set do not disturb from 10:00am until 10:30am. I'm not sure what other kind of timer you'd want.
Maybe there are too many clicks or the interface is hidden?
