Unlock all missions for $2.99 not working – Tower Defense Zone 2 Review

This is a fun and challenging game. I’ve spent hours and hours trying to get to 45 stars in the first 10 maps, but find it is impossible to do so. I’d love to spend the $2.99 to unlock the remaining maps, but that feature does nothing when you click on it. So.... I’m stuck at 42 stars for the first 10 maps. Fix the unlock remaining apps and this will be a 5 start app.
