Hi, so I realised from the comments I still need to query this new field. I’ve added in the query to order posts by date with the newly created field, unfortunately to no avail. Any Ideas:

add_filter('acf/update_value/name=record', 'my_create_a_usable_field', 10, 3);
function my_create_a_usable_field($value, $post_id, $field) {
  // $value will hold a nested array with the rows of the repeater
  if (!is_array($value)) {
    // the repeater is empty, bail early
    return $value;
  }
  $last_row = end($value);
  $date_in = $last_row['date_in'];
  // now put it into a different field
  // this field can be used in queries for filtering and sorting
  update_post_meta($post_id, 'filterable_date_in', $date_in);
}

// args
$args = array(
	'numberposts'	=> -1,
	'post_type'		=> 'post',
	'meta_query'		=> 'filterable_date_in',
	'order'			=> 'ASC',
	'orderby'		=> 'meta_value',
	'meta_type'		=> 'DATETIME'	
);

// query
$the_query = new WP_Query( $args);
