Get_the_post_thumbnail can't define the size of the image

[IacopoC]

Hello,
I'm using this code inside a WP_Query loop,
<?php echo MultiPostThumbnails::get_the_post_thumbnail('products','secondary-image'); ?>
but even if I define a custom add_image_size in functions php,
add_image_size('custom-thumbnail-size', 300, 300, true);
I can't define a custom image size and the thumbnail remain 150px x 150px

I tried in this way:
<?php echo MultiPostThumbnails::get_the_post_thumbnail('custom-thumbnail-size','products','secondary-image'); ?>
Thanks for helping.

If you upload an image before defining a thumbnail size there is no implicit process in WordPress that will retro crop images, you have to use a plugin to regenerate thumbnails. See https://wordpress.org/plugins/regenerate-thumbnails/
