Hello,
I'm still using NopCommerce 3.6; I understand this has been fixed in the newer versions but I cannot upgrade for the time being.
In 3.6, while on the shopping cart page, if a visitor adds a checkout attribute and then goes to another page without clicking on "Update Cart" or "Checkout", the checkout attributes will be lost.
The solution is to call ParseAndSaveCheckoutAttributes() when the visitor moves away. I've read that I should call it via AJAX but how do I implement this?
Any pointers will be much appreciated.
