RevenueCat returns empty customer info

I am having an issue with getting information from RevenueCat products and customer info. I have followed the guidelines step by step, but the delegate returns empty!

First, configuring the SDK:

@main
struct ProjectApp: App {


    init() {

        Purchases.logLevel = .debug
        Purchases.configure(
            with: Configuration.Builder(withAPIKey: "PUBLIC_API_KEY")
                .with(usesStoreKit2IfAvailable: true)
                .build()
        )
        Purchases.shared.delegate = PurchasesDelegateHandler.shared
    }
    .
    .
    .

and then handling delegates using PurchasesDelegateHandler just like the official's sample demo:

class PurchasesDelegateHandler: NSObject, ObservableObject {
    static let shared = PurchasesDelegateHandler()
}
extension PurchasesDelegateHandler: PurchasesDelegate {

    func purchases(_ purchases: Purchases, receivedUpdated customerInfo: CustomerInfo) {
        SubscriptionManager.shared.customerInfo = customerInfo
        print(purchases)
        print(customerInfo.entitlements.all)

    }
}

and here is the debug logs:
