Hi everyone, I'm trying to create a multistore. I did a new group of stores in which I share orders, stock and clients. But when I do a order with one product of each store, the order appears in the first store but not in the others. When I do a order with a product of second and third store, the order appears in the second store. When I do a order with a product of the first and third store the order appears in the first store. If I do a order with just one product, regardless of the store in which I pay, the order appears in the product's shop. So, how can I do the order appears in the all the stores but just with the product of each shop that include the order? Thanks
