Steps to Reproduce (with code)

1. My iOS app is collecting address as an earlier part of the flow (address in the example code below).
2. My Swift code creates a cart using the Storefront SDK like so:

let addressInput = Storefront.CartDeliveryAddressInput.create(address1: .value(address.streetAddress),
                                                                address2: .init(orNull: address.streetLine2),
                                                                city: .value(address.city),
                                                                countryCode: .value(.us),
                                                                firstName: .value(address.firstName),
                                                                lastName: .value(address.lastName),
                                                                provinceCode: .value(address.state),
                                                                zip: .value(address.zipCode))

let cardAddress = Storefront.CartSelectableAddressInput.create(
    address: Storefront.CartAddressInput.create(deliveryAddress: .value(addressInput)),
    selected: .value(true),
    oneTimeUse: .value(true)
)

let buyerIdentityInput = Storefront.CartBuyerIdentityInput.create(email: .value(user.emailAddress()))

let deliveryInput = Storefront.CartDeliveryInput.create(addresses: .value([cardAddress]))

// cartLine created with Storefront.CartLineInput.create
let cartInput = Storefront.CartInput.create(lines: .value([cartLine]),
                                            buyerIdentity: .value(buyerIdentityInput),
                                            delivery: .value(deliveryInput))

let createCartMutation = Storefront.buildMutation { $0
    .cartCreate(input: cartInput) { $0
        .cart { $0
            .id()
            .checkoutUrl()
        }
    }
}

2. With the resulting checkout URL, display Checkout Sheet Kit in SwiftUI via CheckoutSheet(checkout: url)
3. For some users they see a previous address in the CheckoutSheet instead of the current address.

Expected Behavior

I would expect a cart created with a single cart.delivery address, with selected=true, to show that address and only that address.

Actual Behavior

If a user uses our product twice they are sometimes presented the last address passed to CheckoutSheet instead of the current address. I assume there are cookies in play overriding the cart configuration but I can find no way to avoid them.
