Hmm, if your opponent disables chat it will be disabled for both of you during the whole game, but it sounds like you're saying it was like this for all 10 of your games which is odd.
I might have suggested that someone is pranking you by changing your settings:
(live chat near the bottom) https://www.chess.com/settings/live
But your account is only 1 day old, and you're clearly able to post in the forums, so it doesn't seem to be a general restriction.
So I don't know. Maybe some kind of bug. What device are you using to play?
Hi ! It may sounds like a stupid question, but I wonder why is the live chat locked for me, even after verifying my account and playing more than 10 games... Sorry if I'm on the wrong forum, I'm pretty new to that website.
