Here is how I deal with pending transactions in my app
import StoreKit

class PurchaseManager: ObservableObject {
// A printed property to carry out there merchandise
@Printed var merchandise: [Product] = []
// A printed property to trace the standing of transactions
@Printed var transactionState: String = "Idle"
var loadingIndicator: ThreeBubblesLoadingView!
// A set of product identifiers
non-public let productIdentifiers: Set = [
PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID,
PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID_50_OFF,
PaymentHandler.sharedInstance.MONTHLY_PRODUCT_ID,

PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID_FREE_TRIAL,
PaymentHandler.sharedInstance.YEARLY_PRODUCT_ID_50,
PaymentHandler.sharedInstance.MONTHLY_PRODUCT_ID_13
]
// Shared occasion for use all through the app
static let shared = PurchaseManager()
non-public init() {}

Once I make a purchase order, I name the perform purchaseProduct.
Sadly, the pending transaction shouldn’t be being processed. Can somebody please assist? About 5 transactions went via as pending however wasn’t processed by Apple. The fee was not captured. Is that this code improper?
Within the AppDelegate, I’ve the next:
PurchaseManager.shared.listenForTransactionUpdates()
The fee shouldn’t be displaying up in app retailer join and I am not getting an apple server notification about it.
