I tested this again by creating a test product and brand new meta group with variation quantity – I believe it lists as quantities in the group.
When a price is set in woocommerce and NO price in the options or NO default price, it works fine and it is added to cart but what happens is that in the cart, you can change the quantity which should not be allowed.
As soon as you put a price in the Variation quantity and zero in woocommerce, it displays the double price like I mentioned and add to cart doesn’t go through with an error returned.
You guys need to check the plugin for that. I am looking for an alternative at the moment because I am stuck with this. I shouldn’t have updated the plugin.
