yes to confirm this, i reverted back to 195 and games run successfully through XDK.
whatever he is experiencing, I believe it's related since Cordova is also using iOS Safari for the game to run.
Please please find a hotfix for this. I'm working on a time sensitive project. I've never been burnt before by a beta, I will be much more careful in the future moving beyond a stable build.
It must be something minor to freeze up a game at launch preventing the rest of a game to work.
Thanks!
