Has anyone had any luck with preventing multiple users from editing or adding to a shared CardDAV account that syncs contacts across multiple iPhones? I was able to use Jamf to push a set of contacts out to our iPhones through a gsuite cardDAV account but I would love to be able to lock it down for the end users of the phones. This way I can make changes to the contacts and have all users see the changes without everyone and their mom being able to make changes as well.
Any ideas would be super helpful. Thanks!
