setCookies doesn't update cookies in react

Question

I have a problem with setCookies of useCookie library, when i try to save a state to cookies there are no changes, it is very strange because in other parts of the program it works without problems

This is my code:

const [cart,setCart] = useState(null)
const [cookies, setCookies , removeCookies] = useCookies(['cart']);

useEffect(()=>{
    setCart(cookies['cart'])
},[])

const submitOrder = () =>{
    switch (type) {
        case 0:
            if (!cart.home_delivery){
                setCart(prevState => ({
                    ...prevState,
                        ['home_delivery']:[ordine]
                }
                ))
            }else{
                setCart(prevState => ({
                        ...prevState,
                        ['home_delivery']:[...prevState.home_delivery,ordine]
                    }
                ))
            }
            console.log(cart)  //new cart output is right
            setCookies('cart',cart,{path:'/'}) //this doesn't update cookies
        case 1:
            return 'take_away'
        case 2:
            return 'reservation'
        case 3:
            return 'shipping'
    }
}
useEffect(()=>{
    if(cart){
        console.log(cart) //here cart is always right
        setCookies('cart',cart,{path:'/'}) //this doesn't update or changes cookies
        setCookies('cart','some string',{path:'/'})  //this work
    }
},[cart])
