iOS 18 beta removed option to track time in bed with iPhone
Having finally switched to using pure-Apple-ecosystem for sleep tracking, I was curious why I wasn't getting any sort of "time in bed" value recorded (as opposed to time asleep). The previous (iOS-based) tracking app did it just fine.
Turns out it used to be an option that was set on the phone, and iOS 18 seems to have taken it away, but still reports it (as nothing recorded).
Weird.
