Hi @rax
I’ve finaly found a workaround into this issue, but there were 2 changes needed:
- First I needed to change edx-platform code to use settings LANGUAGE_CODE instead of “en” by default when there is no language cookie. There’s a discuss post on this fact Language Configuration Issue on Authn MFE Page - Site Operators - Open edX discussions
- Then I needed to change my MFE to integrate the new ATLAS language processes, so I needed to fork openedx-language to add some custom strings and setup ATLAS_REVISION and ATLAS_REPOSITORY (if you don’t have customized strings I believe you won’t need this change)
Hope this help you to find the solution to your issue
Good luck!
