I've done some tweaking customising with my "out of stock items" for my cart following this walkthrough: https://help.shopify.com/themes/customization/cart/prevent-orders-for-out-of-stock-items (down the bottom to the alert function)
1.) Out of stock notification doesn't appear in the cart "drawer" nor does it appear on the product page.
2.) if I refresh the product page - then it will show a notification saying “all 2 items are in cart."
3.) Can keep clicking more items but no warning notification pops up.
Wondering if anyone else is having this trouble or has a solution, or have I missed something?
