Sorry, I thought I'd be able to find a quick answer to this. My iPad gives little ding tones when an email or message comes in. I thought that if I drop the volume to 0, and get the "no speaker" icon, the iPad would be silent. But I still got the notifications. I tried turning on "Do Not Disturb", but still go the notifications. Is there a simple way to make sure that the thing does not make any sounds at all? Something that can easily be turned on and off? I'm sure there is, but I can't find it. Thanks.
