You are not playing any online games, yet still you get messages about them being paused?
If so I'd send chess.com a helpticket. If you do have games going on, then it may be that your time is up for 1 or mor games and you automatically go into vacation mode. You can change that in settings, but you will lose your game when it happens. Hope it helps.
I keep getting messages that say I am on vacation, or that my games are paused. I am not on vacation, I don't have any paused games, and I find these constant messages telling me to resume non-existant games to be quite annoying. How do I stop them?
