Here you will find any important information when you update EU VAT Enhanced for Magento 2
Updating to version 1.14.0
This version adds the possibility to validate VAT numbers from the UK through the HMRC service. Some refactoring was needed to create a unified way to validate numbers with different interfaces.
Additionally this version adds an adminhtml grid for the VAT number validation results, where you can revalidate or delete validation results manually. We also added new ACL for the admin area, to control who can list, execute a (re)validation and delete results. That means that admin accounts which do not have all permissions, need to have the new permissions added to their role in order to use the validation.
Updating to versions > 1.7
Version 1.7 introduced a new field for the domestic country as well as the shop owners VAT number. You need to make sure that these details are properly configured, as it is one of the factors which is certainly responsible for the descision whether a order gets taxed or not.
The information will be taken from the store address config, as long as there is no domestic country set in the configuration.
