I am pushing updates for some of the subscribers in my list with subscriberAddWithCustomFields:
$result = $cm->subscriberAddWithCustomFields($email, $fullname, array('Vorname' => $firstname, 'Nachname' => $lastname, 'Salutation' => $salut_full, 'Anrede' => $salutation), $list_id, true);
There is a problem — all the fields are updated and confirmation mail fired as a result,
but Name field ($fullname) is not updated.
Everything works fine when updating through CM generated form, but DOES NOT when pushing it via API.
