Contacts Not Syncing

[southerndoc]

I have a Mac Studio running macOS 14.7 and a MacBook Air running 15.0.1.

When I save a new contact with my Mac Studio, it syncs with my iPhone, but not with my MBA. I've toggled Contacts syncing on all devices without resolution.

Is anyone else experiencing this?

I think I found the issue. I think it's something to do with incompatibility of macOS 14.7 and macOS 15.

If I create the contact within "All Contacts" it will sync. I cannot drag it into a list/folder that I previously created when using my Mac Studio on 14.7. However, I can drag/drop to the list/folder when using my MacBook Air on macOS 15. If I drop it into a list with my MBA, it will appear in the correct list on my Mac Studio.

When I created the contact initially, I created it while I the list was selected (so it would automatically put the contact in the list).
