I have tried the solutions mentioned above, and nothing has worked. I can't get a hold of technical support over the weekend so no way to correct this. As of last check, all of my columns were filled in correctly, and the only thing holding me back is no 'Product ID column', which is the first column in the document. I was hoping keeping the filename 'product_import-v2.csv' would help my like the guy above me but still didn't work. Anyone know of any other tips? I transferred it all to Google Sheets and am exporting from there.
