Shopify liquid script does not fetch new products

On my product page in my Shopify webshop I have a small liquid script that looks for other products in the same color and recommends these – output on the page.

So if a product carries the tag mor – it will look through the ‘all’ collection in Shopify for all other products with the tag mor and show them as alternative, matching colour-options.

This works well for all my existing products.

However, today I created to new products with _mor- as tag, and these products are not included in the alternative products when viewing other similar products.

I checked the ‘all’ collection – and the new products ARE part of this collection, but for somehow they are not shown on the product page.

Debug shows that the script does not even evaluate the products – it’s like the products are not part of the fetch of the all collection the script does.

I can’t figure it out. I hoped it was some sort of delay but now it’s lasted for hours – and the two new products are simply not included.

The new products DO show other alternative products, but they are not included when other products try to fetch them.

Below is the code of the script – and here is a couple of products for explaining.

Old product:

• shows all other brown products but not the two new, brown products

Two new brown products:
https://puretime.dk/en/collections/kaffefilterholdere/products/gislev-kaffefilterholder-i-trae-flere-varianter-morkt-egetrae

https://puretime.dk/en/collections/toiletrulleholdere/products/hvidkilde-toiletrulleholder-i-trae-morkt-egetrae-toiletpapirholder

They do show other brown products – but none of them are included in other brown products alternative listings.

Both new products carry both mor and crosslinking tags.

Debug in console is available.
