SKPaymentQueue restoreCompletedTransactions restores same transaction multiple times

Question

I have an auto renewable subscription for 6 months setup up in my purchases via iTunes connect. I created a test user and bought that subscription, now when i try to restore my purchases, it returns the same transaction multiple times in the transactions array in

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions 

I use the following piece of code to restore my purchases.

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

Please advise what i am doing wrong.

Thanks.

Make sure to call finishTransaction.

Answer 2

I have developed storekit for non consumable product. See if you can use it or you can suggest me any changes for the same. :)
Enjoy !
