Saurabh I noticed that the sorting of Variants when you add them on an item is based on time they are created not according to time they are added for each item. If you created Variant "SIZE" today and variant "TOPPINGS" tomorrow, SIZE will always be on top whether you put Toppings first or other first. The earliest created will always be on top. Can you please make it arranged according to when they are added on item itself?
Thanks
