Sharing Screen Time statistics between devices, only having Downtime on some of them?
So I have an iPhone (iOS 13.3.1), an iPad (iPadOS 13.3.1), and a MacBook Pro (macOS Catalina 10.15.3) all with the "Share Across Devices" option turned on using the same Apple ID. This allows me to have aggregate usage statistics about my Screen Time on all of my devices. This also means that they all share the same Downtime schedule.
My goal is to have my iPad and iPhone have the same Downtime schedule and be able to turn off Downtime for my MacBook Pro, while still sharing Screen Time statistics between these devices. Is this possible?
I've noticed recently that there is a (maybe new) setting in the Downtime options called "Block at Downtime" with the explanation "Turn on to block the device at downtime." This setting is also shared between all devices (if I turn it off on my MacBook Pro, it's then turned off on my iPhone and iPad). Can anyone explain what this option does? It seems like it would be exactly what I am looking for, but it's shared across devices.
