Good day support, on both my ecommerce websites, I have set free gift rules during check out:
If customer purchase frozen items :
>$50 small cooler bag
>$100 medium size cooler bag
>$150 large size cooler bag
will be added to cart as a free gift.
The issues is, if customer change the item quantity at cart page, when the cart amount happened to be the threshold amount for eg: $99 to $104, or $148 to $153 which the free gift suppose to be upgraded from small cooler bag to medium cooler bag or medium to large cooler bag, the function is not working, unless I refresh the page.
Both my websites behave differently when it face this issue.
The first website, it will show an empty cart page, which customer will understand that it need a refresh.
The second website, the existing free cooler bag will disappear, even I change the quantity of the cart, no free gift will be added, unless I refresh the page, or add a few more items to the cart.
May I know is there a way to solve this issue? Thanks!
