Here's what's killing me with Insider. It has nothing to make it more robust when connectivity drops, which happens frequently. So if it can't upload a score due to connectivity, it apparently never tries again. Lost many high scores and achievements at home and on route. It really makes me want to avoid the system completely, when you have your best game ever... and it just LOSES IT. It didn't even work for any of the games in the last tournament I played in for several hours. None of my scores even made it to the scoreboard.
