Update: This app I'd no longer worth the time. I used to be able to redeem gift cards, but they now made it so you have to find "membership tokens" to unlock this feature. I'm very angry because after a year, I still haven't unlocked this previously usable feature. I have a feeling it's like the cash portion: the game makes it so you can never quite hit the goal. Developers, let me redeem my tokens for gift cards like before or I'm done playing!
