Ever since I have updated my phone to iOS 11, Do Not Disturb keeps randomly turning itself on for my iPhone 7 (and as a result on my Apple Watch, too). At first I thought maybe it was because DND While Driving was set to Bluetooth and that when my phone was connecting to Bluetooth devices in my home it would mistakingly think I was in a car. However, I have since turned DND While Driving to Manual and the issue persists. I've also checked the DND schedule that I have set (and have had set for as long as that feature was added to iOS) and nothing has changed there. To make sure that wasn't the issue, I turned it off all together and the issue persists at random multiple times throughout the day (which is a major problem for me since I'm a Realtor and am missing calls). Anyone else having this issue, or have any ideas how to address this? Thank you!
