Hi!
Let's see if anyone has suffered this:
I have a multisite with two domains and one language for each domain: Spanish and English.
In English from "store 1", I import the products and later the variants, everything is fine.
Later, I can import the products in Spanish, but when I import the variants, it does nothing, the products in Spanish continue as simple.
If I look at the product in English it appears as a product with variants, if I look at the product in Spanish, it appears as a simple product.
If when I import I tell it to delete the previous combinations, delete the combinations of the other language, for example English, and correctly put the combinations of Spanish.
Thank you very very much.
