Show SKU - Doesn't change when choosing different variant
After following this guide: https://help.shopify.com/themes/customization/products/show-sku-numbers#sectioned-themes
I have tried to do the same as show in example.
Was able to produce SKU same as show in example but when choosing ( changing ) to a different varian SKU stays the same.
Every variant has a different SKU.
We are using Venture theme.
I have followed "sectioned" guide since we have files under "sections".
