I purchased a new iPhone XS Max and restored my iPhone from a iCloud backup when setting it up. Ever since then, Do Not Disturb While Driving has been broken. It doesn’t come on when I start driving my car, and if I try to manually turn it on through command center, it turns itself off. Has anyone had this problem or know of a resolution? iOS 12.01 and 12.1 did not fix the problem. I didn’t have this problem with my old 8 Plus on iOS 12.
