My husband and I have separate Apple IDs. We have family sharing and are able to share our calendars. But we want to share our contacts in a way that is easily accessible on all our computers and devices (Mac OS and iOS.) We keep our computers and devices up to date so we are running recent if not the latest versions of OS and iOS. I have not found a way to share our contacts in the Contacts app without constantly tweaking or creating a third Apple ID, which is too fiddly for me. Is there a third party option that would meet our needs?
