I have iPhone, iPad and Apple Watch. I just set up a sleep schedule in the Heath app on my iPhone and right now I am in my wind-down time (U.K. time zone) so my AW screen is totally black, my iPhone screen dimmed out with a wind-down message on it, but here I am potentially doing whatever I want on my iPad and all devices are on the same AppleID. Did I miss a setting (I did look) or does the Sleep functionality somehow not include the iPad? As my sofa-surfing device my iPad is my biggest distraction late at night, as this post I think demonstrates, so if what I suspect is true that seems a huge omission to me.
