Sorting data on vCard in Contacts
My sister has dropped an email address, but I can't get Mail in iCloud to allow me to select her preferred address. It still uses the old one but does list the next two as options. Unfortunately those are business addresses not her personal one. I thought if I moved her address to the top of the list in her vCard in Contacts on my iMac it would be fixed; I can't find a way to sort the addresses in the vCard. How can I sort them?
