I've been trying to play a game of alternate shot. I use the "Find Any" to find a game. I like this, as the partners aren't always the same, and you get to meet a lot of new characters you wouldn't meet if you stuck to your friends list.
Since Sunday (it is now Monday night in Australia), the Alternate Shot has been hiding the last player in the list from the game controller, which in effect means the game can never tee-off.
I'm not sure if you are already aware of the problem, and it's cause, but it is definitely something that needs to be put on your "priority fix" list.
Thanks
