Thank you for your feedback.
Unfortunately, editing existing lists or creating new lists is not currently possible.
We are working on bringing this functionality to the new Contacts pane as soon as possible. We appreciate your patience and your feedback as we work on making Contacts in Yahoo Mail a more streamlined and unified experience.

I cannot figure out to add a contact to a list. Whoever is in charge of your HCI should be fired!
What kind of software department removes the ability to use lists when it was such an integral part of the mail service?
You should not have removed the option to run Yahoo classic until you had ported all its functionality into the "new and improved" version. This is basic computing 101! Your new Yahoo mail is not "a streamlined and unified experience."
You should have determined by now a time estimate of when the functionality will be restored to lists. When will that be?
Today is April 16, 2019. Let's see how long it takes for you to restore this critical functionality.
