I need to finally, totally, understand how this works. There’s something I don’t get. I find it very complicated.

I can’t get relevant products to show on the product pages.

E.g.. Main shop link – https://sauna.tempurl.host/shop/ (Not styled yet)

Product Category: https://sauna.tempurl.host/products_category/1-2-person-saunas/

You can see in the product category that the products are not relevant.

I need to get this site done ASAP. I hope you can assist me with getting this worked out so future sites are easy for me. Thank you.
