Hello,

Does anyone have a problem with adding product quantity and when you click go to cart the product quantity is still 1?

As seen on the screenshot, the product cost is 14,90€ for one piece. When you add more quantity, it stays 14,90€, when you add to cart it is 1 quantity, and quantity change is available only when you are in the cart, not in the product page.

Hi @Ivan35 ,

Thanks
