Yeah, I think there are hiccups that need to be worked out. They probably should have tested the tech aspects more before releasing it.
I do like it though. The points have increased for foods, but you get more per day, and you have flex points again (this I remember from the US version, although I'm sure the UK had them too at one point). I feel like I have more freedom.
And despite having more "points", it doesn't end up being this crazy amount of food. I don't feel like I'm overeating or anything, and that's with the flex points.
