Chess.com has suddenly become really laggy

It's only happened today and yesterday, Otherwise it's been great. But recently I've been getting a really low fps when playing chess. It isn't an internet issue, and it's likely not a hardware issue. Could someone send me a way to fix this or at least a reason for why this is happening?

Saying it isn't an internet issue, may not be accurate. Issues can occur between you and the site, but not impact your local connection or access to other sites hosted in different locations.

I have been having the same issue. My fan comes on as heat builds up and the moves are painfully slow.

This just became an issue in the last week or so. When I try to open chess.com, I have to wait 1-2 minutes before anything happens. Other websites like Google, eBay, or YouTube open right away, so it's not my computer or connection.
