Did some testing with the facebook integratio and eCommerce. Found 2 BUG’s
I’m not sure but it looks like the Swedish price format is not accepted (valus bigger the 999 SEK). Prices less then 1 000,00 works (999,00 SEK) but prices bigger then 1 000,00 do not work. My guess is the Swedish format with 1 space as thusen separator.
All products are missing the TAG google_product_category.
Se my attached pictures.
