In my app, we offer a free currency, and user only can get it from our free task.Then user can use this currency to subscription( become VIP User ). also, user can get the subscription by paying the in-app purchase products(non-renewing subscriptions). And rejected😢.
Here is the message from review and reply from me.
Apple:"We noticed that your app is using consumable in-app purchase products as intermediary currency for the exchange of items that function as non-renewing subscriptions".
Me:" The currency is not consumable in-app purchase product. User only can get this currency by doing the free tasks".
Apple:"However, we found that your app offers a subscription with a mechanism other than the in-app purchase API. This is not in compliance with the guidelines".
I don't understand.I think this is like that in some games User can get some "Diamond"(Purchase product) by free task. Someone please tell me, is my app doing this wrong? What should i do?😟
