I'm generating offer codes for my app (1 year free). I've generated 500 brand new redemption codes/links, and for some reason none of them work. Navigating to one of the code links just tells me it's expired. I have had a couple people try them and no matter how many times I generate a fresh set, the user gets a code expired message.
Why is this happening? Has anyone experienced this? I've generated working codes before, this issue has just started occurring for me.
Here is one possible cause of this problem. Happened to me a short while ago. I wanted to give promo codes to customers that would give them a free year of the app subscription. However when I generated the code I generated the wrong type of code. I should have generated a "In-App Purchase Promo Codes" but instead I generated a "app promo code". The customer would enter the promo code on their iPhone and when they went to restore the purchase it just said the subscription was expired.
