I have a GMail account that syncs to emClient.
In “Contacts”, I can see the Labels I have in Gmail.
If I go to a contact that has a Gmail Label applied, I can see that label.
However, if I go to a contact and hit “Add Tag”, then “Manage Tags” and select the Gmail account, I am not shown any Gmail “Contact” Labels. - I am only shown “Mail” labels.
So I cannot add a Gmail Contact Label to a contact from within emClient.
If I add a label to a contact in Gmail, it syncs to emClient. If I add a new label, it syncs to emClient. I am just not shown the option of adding any Contact Labels to people in emClient.
