Screen Time not syncing between iPhone and macOS Big Sur

Hey Guys,

I've managed to get Big Sur running on my Hackintosh. Most things work as expected (iMessage, FaceTime etc.). Screen Time is also working on the Mac. The thing is, I also own an iPhone and would like to sync the screen time between the two devices. But no matter what I do, the two devices do not want to sync.

Now the question, does anyone know if this is a Hackintosh specific problem, or is this something that could happen on a real Mac as-well?

Thank in advance!
