Watch out for a virus scam within chess.com. I just made a move and received a pop-up for an "Apple System Notice ... we detected 256 viruses..." directing me to click "OK" to solve the problems. This right as Chess.com has introduced pop-up adds seems they have opened a door making the app less safe for malware. Watch out for it, but also Chess.com tighten up your act. The add pop-ups are a sad evolution while degrading your product.
Did you notice an ad right before that happened?

The site doesn't approve specific ads and sometimes a bad ad can baje it through and staff work on removing them if they occur
