Background of the issue:
I'm using WPML and I want to translate the UK version of the website. However, WPML doesn't support 'UK' as a default language code, so I'm trying to add it as a custom language. The problem is that the slug /uk is already assigned to the default WPML language, Ukrainian, so it doesn't allow me to use uk as the language code for my custom language. My requirement is to use /uk as the URL slug for my custom language only (not for Ukrainian).
Symptoms:
WPML doesn't allow me to use /uk as the language code for my custom language because it is already assigned to Ukrainian.
Questions:
Is there any solution that would allow me to use /uk as the slug for my custom language?
