I put together a little CLI [github.com] to make it easier to play from a Mac. In the process of using it I've found that the GetGamesAndPlayers API method is frequently returning old data.

• Missing games: Sometimes none of my two games will be returned and I'll have to run GetGamesAndPlayers several times to get my games to show up.
  
• Old data: This is the really annoying one. The GetGamesAndPlayers turn data will frequently be stale for as long as 30 minutes. SubmitTurn API method requires turnId from the GetGamesAndPlayers response so you can't complete a turn until GetGamesAndPlayers eventually starts returning the current turn details.
