WHAT DID YOU DO TO CONTACTS? CAN'T EDIT OR MANAGE LISTS. FIX IT!
You completely screwed up how contacts are managed. It's now impossible to add a contact to a list. You are no longer prompted to add a contact to address book. Contacts used to be usable, now they're almost completely useless and undependable. Why do you people keep making Yahoo worse instead of better? This has been going on for like 8 years now.

I hate the new email. I have refreshed, the contact shows in contacts yet I can't add to a list. There is too long of a lag between adding contacts and being able to add to a list. I want to do it immediately. Yahoo needs to listen.
