In magento2.1 add to cart button adds two quantity in cart when you press it for second time. I mean, on product page when add a product to cart it's ok and adds 1 qty. But on second time when I press ADD TO CART, it adds 2 qty and cart qty goes to 3 instead of 2. Also I didn't use amazon payment. what should I do?

  • Is this fresh magento 2 setup? Feb 28 '19 at 5:22
  • if you add it a third time what's the qty in cart? 4,5 or 6?

  • check in view source if catalogAddToCart is not called twice. In my case it happened when I had related product listed down on PDP.
