Photos People Sync

Hey everyone,

I spent 2 hours last night confirming people and adding "unknown" faces to my people app on my MacBook running the latest version of High Sierra. I closed the app and left the laptop plugged into power and connected to WiFi. When I woke up my photos app on my iPhone, iPad Pro, and MacBook were all synced up. The only problem was that they were synced to the "old" library with the old faces. So it was like I hadn't done any of the work to organize that faces at all.

Is there a way to set one of my devices to be the "Master" in the case of sync issues like that? Or is there a default "Master" that I should be using for my editing and organizing? It seems logical to me that the laptop would be the easiest and therefore the best choice to be that sync issue solver.

Anyways thanks for any tips/help on this issue.
