Contacts on Mac don't sync to iCloud
Once again I'm adding contacts to the Contact app on my MacBook Pro and they don't sync up to iCloud so it doesn't sync with my iPhone. Nothing changes it just stops syncing.
Short of using another contact app from a 3rd party does anyone have any suggestions/help?
I went through this with apple support many months ago and it just started working but again not working once again (probably the 4th or 5th time I've experienced this).
Thanks
MacBook Pro, macOS High Sierra (10.13.2)
