Cancelled my diamond membership a few weeks ago because they don't have this feature. I still play here, I just won't be paying for it until we have confirm move.
Confirm Move Button?
It's actually pathetic they don't have it in PC. I lose all the time because I accidentally finger slip
chek settings
Better ditch the chess.com and use lichess cause they have this function implemented. It doesn't seem like chess.com even cares.

+1 I'm so serious I won't be renewing my diamond membership if this isn't added before my renewal
