restarting the phone and refreshing the page was no help
blank chess board

I was playing on the web site, Galaxy Note Edge, in this game, hit the edge which switched me to the game in the app. I returned to the game in the Web and the board came back blank. I can see all the correct pieces when I view all the games in progress, but when I select this one game it's blank
Get the app for your phone. Mobile websites sometimes does something weird. And, the app imo is better than the website anyway.
one of my games on the Web site, using my phone has a blank board. I can use the app to make moves.
