If you have a number of products that are in essence the same, such as a nail varnish with 50 colours, the quickest way to add the products and update the regulations, such as recycle logos is as follows (TL;DR - simply add one product and duplicate it):-

Step 1

Go to the product you have added in your product collection. Click on the three dots on the right of the product listing, you should see the following options. Click Duplicate

Step 2

You'll see a pop-up, click ok.

Step 3

You'll see a warning, this is normal, in order to save you from actually having multiple GTIN numbers that are the same, we add the word 'DUPLICATE' after GTIN number and (duplicate) after the SKU - and title of the product.

Step 4

Simply visit each product, edit the title, add the correct SKU, and replace the GTIN for the correct one. When you click save, the errors will disappear and the recycling logos will be attached to the new product.
