I added my contacts to my Mac via CardDAV (because of lack of Exchange support).
I can see my contacts show up right away in the Contacts app.
I cannot edit any of the contacts details. When I click edit on the contact, it goes into edit mode, but any of the phone numbers or email addresses that are on the Contact in Zoho are just plain text and not an editable field.
Anything I add does not sync back to Zoho.
Is Zoho CardDAV view only?
