Chess.com has major issues the site lags from ads and makes playing near impossible, limited chess problems to three a day, consistent failure to punish people that escape. Of course you can solves the lag by just using the app till they start slapping ad banners and a video ad every 10 minutes like every other a cheep mobile game and you can just use lichess for problems but eventually if things don't shape up ppl will jump ship whole sale.
There are ads?!
I don't know but lately chess.com is lagging heavily. It's not fault of my internet connection as I have double checked this fact by playing on other chess site side by side with the same connection. It feels kinda bad when you lose by timeout in a winning position in hyperbullet and bullet tournaments specially.
Hope you will do something about it....
