Format and navigation sucks!
Hate the (Improved) New Yahoo mail! The message area has the least real estate on the screen. Have to scroll side to side and up and down to read messages. I'm here to read mail, not be entertained or sold something. Multiple steps now require to access other mailboxes! Will be moving to Protonmail as they seem to really care about the customer experience!
Too bad "Format" isn't one of you subject categories! Just shows your lack of understanding as to why users are actually using email.
