Hi Guys,

I am developing IOS purchases on a physical device.
Everything was working fine until I upgrade to IOS 14 version.

Device: Physical iPhone 6
IOS: 14

IT iS NOT RESOLVED YET.

The problem:

Before making a purchase I send to verify the restore purchases with my backend.
I check that the user does not have active subscriptions
If the user does not have active subscriptions, I will send him to buy a subscription
The purchase popup never appears

This happens with users who have already made a purchase before.
I tried removing the call from the restore purchases and it works fine without this one.

Code Block RCT_EXPORT_METHOD(getAvailableItems:(RCTPromiseResolveBlock)resolve
                  reject:(RCTPromiseRejectBlock)reject) {
    NSLog(@"\n  getAvailableItems \n ");
    [self addPromiseForKey:@"availableItems" resolve:resolve reject:reject];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

Code Block -(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {  ////////   RESTORE
    NSLog(@"\n\n\n  paymentQueueRestoreCompletedTransactionsFinished  \n\n.");
    NSMutableArray* items = [NSMutableArray arrayWithCapacity:queue.transactions.count];
    for(SKPaymentTransaction *transaction in queue.transactions) {
        if(transaction.transactionState == SKPaymentTransactionStateRestored
           || transaction.transactionState == SKPaymentTransactionStatePurchased) {
            [self getPurchaseData:transaction withBlock:^(NSDictionary *restored) {
                [items addObject:restored];
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            }];
        }
    }
    NSLog(@"\n  paymentQueueRestoreCompletedTransactionsFinished : %@", items);
    [self resolvePromisesForKey:@"availableItems" value:items];
}

Code Block -(void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error {
    NSLog(@"\n  paymentQueueError \n ");
    dispatch_sync(myQueue, ^{
        [self rejectPromisesForKey:@"availableItems" code:[self standardErrorCode:(int)error.code]
                           message:error.localizedDescription error:error];
    });
    NSLog(@"\n\n\n restoreCompletedTransactionsFailedWithError \n\n.");
}

Code Block RCT_EXPORT_METHOD(buyProduct:(NSString*)sku
                  andDangerouslyFinishTransactionAutomatically:(BOOL)finishAutomatically
                  resolve:(RCTPromiseResolveBlock)resolve
                  reject:(RCTPromiseRejectBlock)reject) {
    pendingTransactionWithAutoFinish = finishAutomatically;
    SKProduct *product;
    @synchronized (validProducts) {
        for (SKProduct *p in validProducts) {
            if([sku isEqualToString:p.productIdentifier]) {
                product = p;
                break;
            }
        }
    }
    if (product) {
        [self addPromiseForKey:product.productIdentifier resolve:resolve reject:reject];
            
        SKMutablePayment *payment = [SKMutablePayment paymentWithProduct:product];
        [[SKPaymentQueue defaultQueue] addPayment:payment];
    } else {
        if (hasListeners) {
            NSDictionary *err = [NSDictionary dictionaryWithObjectsAndKeys:
                                 @"Invalid product ID.", @"debugMessage",
                                 @"E_DEVELOPER_ERROR", @"code",
                                 @"Invalid product ID.", @"message",
                                 sku, @"productId",
                                 nil
                                 ];
            [self sendEventWithName:@"purchase-error" body:err];
        }
        reject(@"E_DEVELOPER_ERROR", @"Invalid product ID.", nil);
    }
}

It is the library react-native-iap that I am using
