Out Of Stock Notification Not Indicated On Side Cart

Hi, but I don’t understand why the theme was created without this feature in the first place, especially since it came with a side cart. This shouldn’t be something special that requires customization beyond what the theme provided. This is an essential feature to have. How else will the customers know that items they’ve already added to their side carts, were no longer available for purchases? This is a common thing that I’ve noticed all the time on other websites. That once an item gets sold out while inside the side cart, a notification message, usually written in red, would indicate that the item was no longer available. Or sometimes the message would have other things along with the texts.

Hi, I was taking about the “side cart”, not the actual cart page. I was told by my developer that the side cart was a theme feature and not a WooCommerce feature, so the notification alert when an item is no longer available after someone already added an item to their side cart (not cart page), should be connected to the theme. Are you saying that such “side cart” notification is a WooCommerce thing? Please see screenshot of the side cart I was referring to.
