I just wanted to point out a couple of errors I found in this module (version 2.0.9, under Prestashop 22.214.171.124), in case the devs would like to fix them:
- Availability data (like in_stock, backorder, etc.) is filled in the "availability date" column instead of the "availability" column.
- The column for brand data is incorrectly titled "Brand name". The oficial attribute's name is "brand" (as you can see in Google's product data specification here). This causes merchant center not getting this data right.
