[Resolved] Language Switcher doesn't work for a specific page

Problem:
The client was experiencing an issue where the Language Switcher did not display the English flag on the French site and showed no flags on the English site. The hreflang attribute was missing for English from both pages, even though the pages were translated.
Solution:
We recommended the following steps:
1. Verify that the two pages are connected by checking in the default language view. The client should edit the page and ensure that the translation shows a "pencil" icon. Then, use the language switcher at the top (making sure to exit the Gutenberg fullscreen if necessary) to switch to the translated version and check if it displays correctly.
2. We suggested adding a footer language switcher via WPML->Languages and checking if the same issue occurs with the footer language switcher, ensuring it is set as a list and not a dropdown.

If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum.
