if i set my status as "ready for a game" (blue) my friends tell me they cannot send me invites ??? is this correct, and why should that be ?
Are you by any chance playing on a mobile device and your friends on PC's? If you are then that's the problem, the game doesn't allow cross platform play.
If not then I'm afraid I have no idea, I've never had that problem.
Good luck.
Dont know about your friends but you are on my Do Not Play List
