Today i requested 10 promo codes for my new update, Apple email me like thisromotional codes provide free downloads of your application, and can be used before the application is available for sale on the App Store. My app is now automatically Ready For Sale. Does it means the promo code can not be used right now? How can my followers correctly use my codes?
Of course the codes are going to work after the app is released. They just meant to say that you can also use the codes before the app is released. Codes work for about 28 days from the date they were generated and wont expire even if your app gets updated before 28 days.
