Adjusting crop area of thumbnails in woocommerce

Hello,
I want to change my woocommerce thumbnails so they crop the thumbnails from the top, center instead of from the middle of the image. I added code to my functions.php file in my child theme.
add_filter( ‘woocommerce_get_image_size_gallery_thumbnail’, ‘enfold_child_set_gallery_thumbnail_crop’ );

function enfold_child_set_gallery_thumbnail_crop( $size ) {
$size = array(
‘width’ => 450,
‘height’ => 450,
‘crop’ => array( ‘center’, ‘top’ ),
);
return $size;
}
I then regenerated the thumbnails through woocommerce. It works on my personal computer, I can see the results I intended. However it does not show up on my Ipad, my phone, and no one else I show the site to is seeing it. We aren’t using a caching plugin. Tried waiting over night, and it didn’t work the next day either. They’ve tried shift reloading as well, it’s not showing for them either. I’ve also tried regenerating the thumbnails with a regenerate thumbnails plugin. Is there a step I am missing, or a conflict that would prevent that from working properly? I can’t figure out why I can see it but no one else can.
