Seemed okay when I checked your account:

I had the same issue some days ago. I think there was some cache in my browser causing it. The issue went away after closing and opening my browser.
It happens with me too, sometimes.
I clear browsing data and it comes back to normal. Sometimes, refreshing the page works too.
I have notification with 1 game "your move" but when i bring my mouse over the icon "play" there is no avtive games.
