Not sure how this functions on the PC but this is what happens on my iPad v2 with iOS 7.0.4.
I have finished 2 multiplayer games. They are listed in the results section, current game tab in the multiplayer accept a challenge screen. When I highlight a game and tap the Play button, I get a pop up that says "downloading the game....", with a turning cog icon. Only problem is that the icon stops turning and the application hangs.
I can't revisit my results.

Is this a known issue and what functionality am I to expect if this was working? Any help would be appreciated.
