Problem:
When using different domain per language wp-admin and pages in the hidden language was not accessible even though user had already set "Display hidden languages" from the profile editor.

Solution:

- Clear cookies on all domains and browser cache.

- Check "Auto sign-in and sign-out users from all domains" at WPML -> Languages.
