Background of the issue:
I set up the language switcher to show in a menu, but it does not work. For now, I set up the languages to show in the footer, but I need the language switcher also in the header menu. I already looked at this issue (https://wpml.org/forums/topic/menu-language-switcher-is-not-showing/) but my menu is set up correctly.
Symptoms:
The language switcher is not showing in the header menu. Instead, I got nothing.
Questions:
Why is the language switcher not appearing in the header menu?
How can I ensure the language switcher is correctly set up in the header menu?
