Hello, RT2012,
Thank you for choosing XStore as your WooCommerce WordPress theme.
Translation files of the theme should be placed in /wp-content/languages/themes/ folder,
plugins, like Core plugin, in /wp-content/languages/plugins folder, then you will not lose translation after updates.
We regret to inform you that we are unable to assist you with adding products to Google Shopping, as this falls outside of our support scope. We are only able to provide assistance with questions that are directly related to our theme.
If you have any additional questions or concerns, please do not hesitate to reach out to us. Our support team is always available to assist you.
Kind Regards,
8theme team
