What’s the path to that screen?
My own experience with iOS 14 and watchOS 7 has been bedeviled by the “Health” app, whose “Sleep/Wake tracking” is ruining my sleep! I played with the sleep tracking features after installing the new watchOS on my Apple Watch 5, only to discover that I’d created an inextinguishable Zombie who insisted on waking me up every morning at 6 am to the tune of an alarm sound I’d never heard before. I figured out how to turn all that stuff on the watch pretty quickly, but then the alarm came from my phone instead, and there I eventually discovered that turning off the wakeup alarm only did it for the next day, that TRYING to turn it off for EVERY day (in the Sleep section of the Health app) is not possible (one cannot deselect every one of the day of the week headers), but that it IS possible to delete the entire iPhone Sleep/wake monitoring. Even THEN, it’s presence remains in the iPhone Clock app, where it just tells you that no sleep/wake alarms are set. With an interface as jumbled as that, 32 PB may not be enough!
