They're obviously still working out some bugs, my Store app shows that I have Fruit Ninja installed but I don't. I had the trial app back during the beta but I never purchased it. It tried to "update" the game now but fails every time. Kind of annoying... hope this stuff gets fixed by Friday.
Uninstall the game, then go back into the store and look at games/apps you haven't installed.
There you will find Fruit Ninja waiting to be installed...and it's the full version. I'm not sure if it was intentional or not. I then went to the store and checked the normal listing for it and it had the $4.99 price. I clicked the option to buy it (figuring why not see what happens) and it asked for my password, and didn't charge me.
I checked my billing and transaction history...so either it's an issue where they are giving it out for free and didn't mean to...or it's a little thank you gift that they don't mention for the earlier build users.
I'm hoping it's the latter since I quite enjoy the game and yes it does work for me.
Wow, I've not really used a whole load of the apps but just realized today that I can't have an app open on each of my monitors at the same time.
That's a good design choice. /sarcasm
Sarcasm not needed...that's what Snap is for...but you didn't watch the tutorial or read any documentation I can see
