Many bugs

This app is very useful when you have it all set up and ready to go, but after not logging into it my information for my login goes away and I have to keep re logging in. Personally its annoying because Im having issues with my power up rewards account. Another problem is the pre orders when I go to pick it up or if I dont pick it up on the exact date of the launch it says that it was canceled and I couldnt find a way of deleting the game from the list. Would love the app much more if it was fixed, thank you. Just an update now it completely wont let me log in this is a shame because I want to check my preorders and such making the app pretty useless to me, please fix...
