Xbox design lab controllers not being shipped to Northern Ireland

Hello, when the new Xbox design lab opened I was excited to get a new customized controller for my new series x. I had already used design lab before to create two other custom controllers for my Xbox one. They was made and shipped to me with ease. So when I designed my new controller today and got to the shipping it said that it could not be shipped to Northern Ireland, I was able to ship to England easily but not Northern Ireland. I was wondering why this is and if they will eventually make it so they can be shipped as I am pretty bummed out that I can't get one. Thanks for your time in advance!
