It shows up on mine. You have a bug.
Disappearance of "Open Challenges"?

Nioe he doesn't have a bug. It aint on my browser either. Tested on Firefox and Chrome, mobile and desktop....the link was removed.

Pardon the slight thread necromancy, but open challenges for daily games are still missing. I can find the link when clicking "play|daily Chess and then the time limit button in the New Game section, but clicking open challenges on the form that appears results in a blank list.

@JHBlackburne I checked and open challenges is working. If it was blank it may have been there were no challenges at that time. To the right of the name open challenges is a refresh button (round circle arrow). Tap/click that until you see a challenge you are interested in .
It appears that the "Open Challenges" section has disappeared for Daily Games. Is this true or am I missing something?
