## Code

```php
add_filter( 'pll_preferred_language', function ( $slug ) {
    if ( ! is_user_logged_in() || ! function_exists( 'pll_languages_list' ) ) {
        return $slug;
    }

    $user_locale = get_user_meta( get_current_user_id(), 'locale', true );

    if ( ! $user_locale ) {
        return $slug;
    }

    $locales = pll_languages_list( array( 'fields' => 'locale' ) );
    $slugs   = pll_languages_list( array( 'fields' => 'slug' ) );
    $index   = array_search( $user_locale, $locales, true );

    return false !== $index && isset( $slugs[ $index ] ) ? $slugs[ $index ] : $slug;
} );
```

## Notes

Only applies when the profile language is one of your Polylang languages; otherwise Polylang's normal detection runs.
