Tax Rule Only Working for Tax Category

Hello guys,

On v15, it seems impossible to create tax rules based on the customers country ( from Billing Address ), and also for the Customer Group or Item Group.

I can only make the Tax rules work with the Tax Category (which is inserted at the Customer Tax Tab).

Why is that?

I have noticed that the Country field at the Tax Rule is called “billing_country”. While the Address Country is called just “country”.

Without the Tax Rules working it becomes hard to adapt to Customera from International Countries.

Is this a bug or on purpose?
