Contacts will not sync properly between Mac and iPhone
This is angering me very much. I have an iPhone 7 running iOS 11.2.6 and a MacBook Air running Mac OS 10.13.3 and no matter what I do, I cannot get them to properly sync contacts anymore. They used to sync fine. But now, I create a contact on my iPhone and it will sync it over to my Mac but any updates I make, either on iPhone or Mac, refuse to sync. I am getting extremely frustrated with this, I have been using Apple products for over 20 years and never had this kind of issue. Everything else seems to sync, calendars, notes, reminders, photos, call logs, etc. I purposely go out and spend all this money on Apple devices so I DON'T have to deal with these kinds of problems, yet this has been going on for a few months now, they simply will not properly sync contact info! I keep trying to give Apple time to fix it, yet come every update it never seems to get fixed. Why am I not able to properly sync my contacts!?!?
MacBook Air, macOS High Sierra (10.13)
