Disappearing contact photos Apple's Contacts app has been acting up for me recently. About the same time that iCloud sync stopped working I noticed that when assigning photos to contacts, they don't stay saved. They appear to be saved at first but when returning to the same contact card a minute later or so, the photo is gone.

Is anyone else having this issue? Any ideas how to fix it? I'm using macOS 10.13 on a 2017 MacBook Pro and iOS 11 on an iPhone 7.
OK well I tried the following:


Turning off and on the contacts toggle switch on both the mac and the iPhone simultaneously. No effect. 
Turning off iCloud on both the mac and the iPhone simultaneously. And then on. No effect. 
Signing out of iCloud on both the mac and the iPhone simultaneously and then logging back in. This was a painful process but seemed to have solved the issue.
