Hi there, I hope you are well! I have installed WPGraphQL, WPML Multilingual CMS, and WPML GraphQL on this website locally. As part of this development, we have added a custom language (using the uk code for an English version of the website) and have created pages in the /uk/ subfolder approach. The WPML GraphQL plugin states that 1.2.0 allows for URI based lookups, however if I try and get a home page (e.g. /uk/home/ or /uk/another-page-url/) it only ever loads the default language version, not the UK version. I can see the UK versions if I fetch all pages and use the where language query parameter, but I am not directly able to fetch a page by the URI.
The issue is still confirmed and has already been identified as a missing corner case in the implementation of URI resolution for translated homepages. Unfortunately, it has not been fixed yet.
At the moment, the developers are focused on the WPML 5 release, and they plan to resume work on this issue once that work is completed. Therefore, I don't have an estimated release date yet.
I'll keep your ticket linked to the internal issue so we can notify you as soon as there is any progress or a fix available.
