I'm running a MacBook Pro with the latest OS and a iPhone 7 with iOS 11.4.1. The Calendar on my MacBook Pro and iPhone 7 sync fine with each other. When I put something in Contacts on my iPhone, it shows up on the MacBook Pro. However, if I put something in Contacts on the MacBook Pro, it doesn't show up on the iPhone. Do I have a wrong setting somewhere? Thank you in advance for your expertise and assistance.
