No error, but no results also.

$query_array = array('relation' => 'OR');
    array_push($query_array,
    array(
      'key' => 'filter1',
      'value' => array('value1', 'value2', 'value3'),
      'compare' => 'IN'
    )
  );

No results.

$query_array = array('relation' => 'OR');
    array_push($query_array,
    array(
      'key' => 'filter1',
      'value' => 'value3',
      'compare' => 'LIKE'
    )
  );

Works like it should (but with one filter), but when I use array('value1', 'value2', 'value3') i got nothing again.

PS. I am filtering by ACF value.
