PHP Notice: directly accessing product properties:

(This message was added in version 3.0.) in /app/public/wp-includes/functions.php on line 4773

Example: $product->id though it looks like there are other places too.

This was deprecated in WooCommerce 3.0 and should be replaced with $product->get_id()

Looks like I already took a pass at this 2 years ago in #11.
