Provide configuration for shipping business days for a country or the whole offer in a way that doesn’t conflict each other
In this article
Why this issue is happening
When multiple handling business days or transit business days are configured to the same country or the same offer to all the countries, it creates ambiguity to select which attribute to choose, so neither of the attributes are chosen.
