In my store, there is 1 main item with 3 different variants (ex: 5ft,6ft,9ft), each is a different item/sku
When I tried the 'Add Items as Shopify Variants', it gave me this error
Items cannot be added as variants to a product with the "UoM as Variant" setting enabled for this store.
I watched the YouTube tutorial, but they don't have this issue. How can I enable this?
