[Closed] custom functionality help

Hello,

im creating a custom functionality that is triggering on trash/untrash/delete and need to switch language and then do trash/untrash/delete of that post. The problem is that im always getting the english version of the post. For lng switching im using

global $sitepress;
$sitepress->switch_lang($post_language);

checked, post_language is returning good string 'es'. Am i missing something?

Things to mention, im using this on multisite, and switch_to_blog is working fine
