Language switch shortcode not working in mobile

Hello,

I’ve a problem with my language switcher in my mobile version.
First, it is defined by shortcode with these settings :
pll_the_languages( array( 'dropdown' => 1, 'show_flags' => 0,'show_names' => 0, 'display_names_as' => 'slug', 'hide_current'=> 1) );

On mobile version, when I select another language, it doesn’t change from page.
Could you please help me ?

Thanks.
