V2 is still alive. I, like many others am now using the fairly bug free aspect of V3 for live Chess, and what is still highly useful on V2, even if has been mangled, for the posting and "social" aspects of Chess.com
The above link will tell you how a few of us have managed to persuade the management that V3 is still a work in progress, which is my best way to put it diplomatically, and as non-controversially as I can manage.
You may have to join the group/club chess-com-v2 to read the story of an interesting series of exchanges with the management over a long period.
@camter Thank you, I have the three points now inserted at 36 ...Rc1+.
@game_designer I am also using v3.
