Hi Eduardo,
It's not working ..
I add a product with a tax of 0 % to create the attribute.
I you have some time for me, I setup a NOP Commerce 4.10 solution to test this.
I invite you to connect with those value :
url : http://shop.shop2u.be
user :
[email protected] pass : admin
The test (and only) product is in BIERES BELGES --> BLANCHE DE CHARLEROI
It's a test environnement you can make all tests you want.
(feel free to switch to English language when you are logged …)
