I have the same problem! I use RNIAP.finishTransaction(purchase) after the receipt checking everything works until i use getPurchaseHistory() / getAvailablePurchase() when i use the above functions, clicking the subscription button become checking the old receipt validation, instead of showing the purchase

I think you shouldn't be doing the validation in the client side if the user try to intercept the requests with a proxy and override the IOS_IAP_SECRET by Reverse engineering your app this should give premium access or features with a very simple atack

Hi @Ulisses1478 Thanks for your answer, but my question was different. In real life backend checks receipt.

Use the latest version of the library and use finishTransaction
