I don't play the UK version as I live in the United States but I wanted to try and see what it shows when you type in the link that takes you to the UK version of the game. The link was posted under my alliance page in General chat on Discord.
The picture below is what is shown when you try to get on the UK version and then once you click the button it takes you right to the MissionChief login page.
I figured I would point this out to those who do play out of the UK.
