Shipping rate is not updating when signed in

[fareedkamal]

I'm using codebase from woonext app pro. i'm encountering an issue where the shipping rate doesn't update while signed in but it works as guest.

On my woocommerce store i have shipping rates saved. for US its 8$ and some label and other info. for rest of world its 20$
after updateCart i get the response cart object with correct shipping rate and total when im as guest. when im signed as a registered user and change country, the shipping rate is fixed to 8$

here's the logic that i've implemented for updating shipping rate.

in my checkout form , if the country is changed the below function is triggered

const { setShippingLocale } = useOtherCartMutations(sessionContext);
const { cart: cartData, updateCart } = useSession();

const updateShippingRate = async () => {
try {

  await setShippingLocale({
    country: formik.values.billing.country,
    city: formik.values.billing.city,
    state: formik.values.billing.state,
    postcode: formik.values.billing.postcode,
  });

  await updateCart({
    mutation: 'updateItemQuantities',
    input: {
      items: [
        {
          key: cart?.contents?.nodes[0].key as string,
          quantity: cart?.contents?.nodes[0].quantity as number,
        },
      ],
    },
  });

} catch (error) {
  console.log(error);
}

};

u can reference the sessionOperations.tsx file and the app/api/cart/route.ts file from woonext app pro
