The faulty one is still for sale at amazon; the faulty downloads are still on itunes; they never replaced the last faulty version of this title. I'd say bring it back to the store and wait to repurchase until you know it's been fixed. I think they will continue to sell stock they have until it is exhausted, and maybe even reprint; the percentage of returns may be low, the costs and trouble of resetting it quite high. Maybe it will get redone, but we're not aware of any firm commitment, and keeping the faulty version on sale looks like a commitment to something else...
