Cannot list a UK ASIN on DE or NL site



I have started to push some products out into DE and NL.

I started the process in February, then covid came along and until this week have been too busy to push overseas further.

I am now refocusing on DE & NL as I wish to build some traction in these countries.

Anyhow, I have used both the Build International Listings Tool, and the Edit product page to try to get two of my UK listings appearing on the DE and NL pages, but with no effect. They simply don’t show up.

Indeed, when I search for the ASINs on the German page, they say that there is no ASIN of that number in their catalogue.

It’s very frustrating.

Could anybody shed any light - and possibly a solution - on this please?

Thank you,
