Previously it was easy to add a contact to a list while editing that contact. Now you have to go to the list and add a contact by typing that contact name or address, but some of the contacts won't pull up that are in the contact list. Any suggestions? Can I go back to the old versions and simply edit a contact and add them to a list there?
I don't use yahoo, and not sure if this method is still applicable, but try this: https://www.groovypost.com/news/switch-yahoo-mail-back-to-classic-view/
