Hi Vossie75, there’s a fix in the next Plugin update that sorts the missing Product Attribute export fields from the Product and Order export types.
Regarding Brands support we do support exporting Brands from WooCommerce Brands (http://www.woothemes.com/products/brands/), it could be that something has changed in their Plugin and we no longer are detecting the Brands correctly but as of the current release it seems to be working… can you confirm the Plugin name as well as Plugin version of WooCommerce Brands so I can look into this further 🙂
Do you want to filter Products by Brand within the scheduled export or CRON engine? I think we support Brands already via scheduled export.
(glad to hear prices are working again!)
