The link to a collection doesn't work if referral code is added on the NL site

[MaxT]

When I open the link to a collection of products that I've made, it opens

correctly, without my referral code: https://www.zazzle.nl/collecties/promotie_materiaal-119653580734603484

but incorrectly, with my referral code: https://www.zazzle.nl/collecties/promotie_materiaal-119653580734603484?rf=238874667569860182

Instead, it opens a landing page of trending collections.

I also tried to open this link in a different browser, and it seemed to work the first time, but not the second time. So if you're going to test this, please open it at least twice.

Someone helped me out a bit and turned the links into ones pointing to the US site. On the US site, the links do correctly go to my collection. Even the one with my referral code added.

Here's the US link with my referral code added, which works correctly: https://www.zazzle.com/collections/119653580734603484?rf=238874667569860182

So, is this issue related to the NL site?

This is what I see:

from what you say is an incorrect link

Apparently, referrals are stipped for none  .com   domains. 

I think I read that somewhere? For example, if I share a .com link and the customer switches to co.uk I lose the referral.

Referrals seem to work on products with a NL domain for me. I think it might be an issue with the collection functionality of Zazzle + different domains.

For example, I also can't make an RSS feed with a NL domain, it only works with US. Which probably means that they've implemented this functionality for US domains, but not for others.

But collections should definitely be available for all domains...

@AnneDid you try more than once? When I tested, it went to the collection the first time and a page full of other people's collections the second.

You're right, @Badeesie . Today I checked your link
https://www.zazzle.nl/collecties/promotie_materiaal-119653580734603484?rf=238874667569860182
again and it could not find your collection.
@CreativeLeahG  Even if the referral is stripped (which is awful in my view), it should show the correct collection and not be weasly saying "we can't find it". 
I am wondering whether it makes a difference if a collection is created on another country domain or on .com?
