Well it took me a day of searching, but I hit upon the solution. Hope this helps someone to avoid the same trouble.
<?php
$values = get_field('notes_added');
if($values)
echo'<h1>Notes</h1>';
{
foreach ($values as $value){
echo '<table><tr><td>'.$value['user_meta']['nickname'].'</td><td>'.$value['note_text'].'</td></tr></table>';
}
}
?>
