I have setup a product which has multiple variations as the image shows:
My variations have a colour taxonomy which I'm trying to use for when a user wishes to switch between variations on the same product.
My problem is the product node is not presenting any option for selecting the list of available colour nor is there an add to cart form.
I'm sure I'm missing one or two things ... I could use a second opinion, please.
UPDATE:
I already had the "Enable this field to function as an attribute field on Add to Cart forms" selected but didn't work.
I noticed in step#2 of the answer you directed me to, the taxonomy field is created in a Variation entity type.
However, I don't see a Variation entity listed on my site.
I'm adding my colour taxonomy field into the product type entity as shown in the image below:
