Hi there,
I have added my products, created a new shipping profile but when I want to add products to it, it only shows 8 products, instead of all of them.
What can cause this problem?
I would give more information, and include screenshots. That should help someone to help you better.
Based on the information you’ve given so far, my best guess is that the products are not published, or for some reason not able to be added to the profile you created, based on the settings.
You could try the shipping profile documentation too, that may help: https://help.shopify.com/en/manual/shipping/setting-up-and-managing-your-shipping/shipping-profiles
