I wanted to add new quote item (new row on cart page) when the product quantity is more than 1. I already tried accepted answer provided here. Whenever I tried to add existing cart item from 'product-details' page the given solution is working.
The problem I am facing is when someone change the quantity from 'checkout/cart' page, above solution is not working.
Can anyone provide solution for this. I am using magento version 2.2.7
