You've been able to access the app forever, you just can't place a bet. Even more annoyingly you can't sell or close a ticket when it's in the money. Many times I would have love to cash out and take my win in the 3rd quarter of a game only to watch my bet blow up by the end of the game.

Edit: To be clear I'd place bets while up in NH visiting family but couldn't close them out once back in MA. Just had to let them ride.
