I have an application that contains auto-renewable subscription products in app. Everything works fine, I can purchase, upgrade, downgrade and restore purchase but promo code redemption.
I generated promo code for one of subscription and tried to redeem in App Store app. The alert appeared and said "Error, Code redemption is temporarily unavailable. Try again later".
I also generated new promo code and tried on another device with difference Apple Id and result is the same.
When I tried a promo code redeemed at first, The alert said "Error, This offer has already been redeemed by another account".
I use https://github.com/bizz84/SwiftyStoreKit for processing the purchase. Tested on iPhone XS (iOS 13.1.3) and iPhone 6S (iOS 13.1)
I submitted case to Apple Developer Support but no one reply to me.
How can I resolve the this issue? Does anything I miss to implement?
Appreciate for any help! Thank you. 🙏
Guysss. The problem was fixed. I can redeem the promo code and get it by restore purchase in app.
