When the new updated version of the extension is applied, all former customizations will no longer exist. Thus, please check carefully again with your coordinates before doing it. Besides, don’t forget to back-up your data and package to avoid unexpected events.
With the customization on your extension made by Magestore before, we do not offer Free for re-customizing, however, a special rate will be applied so that you can have the customization for the new updated extension within the lowest cost :). You can refer the full Term and Condition of Customization Service for more details.
