Hello luoy,
I'm sorry for any confusion, in my original message, the line 'Via Types, I've setup a new CPT called "Products"' should be 'Via Types, I've setup a new CPT called "My Products"'.
So you're right, I'm talking about the Custom Post Type "My Products".
If I understand correctly, it would not be possible with CRED to work with product variations? The product links (see screenshot) for both the WooCommerce order process and the CRED order process are the same though.
