function related_post_acf_shortcode( $atts ) {
  // extract attributs
  extract( shortcode_atts( array(
    'field'      => '',
    'related_field' => '',
    'post_id'    => false,
    'format_value'  => true
  ), $atts ) );
  // get unformatted value of post object field
  $related_post_id = get_field($field, $post_id, false);
  // get value from the related post and return int
  $value = get_field( $related_field, $related_post_id, $format_value);
  // array
  if( is_array($value) ) {
    $value = @implode( ', ', $value );
  }
  // return
  return $value;
}
add_shortcode('related_post_acf', 'related_post_acf_shortcode');

/*
  shortcode
  
  [related_post_acf field="post_object_field_name" related_field="field_name_on_other_post"]
