Hi @make-carlos,
you mean by “custom options” = “custom fields”? If yes – we use the standard function/hook “ordered_again” and “custom options” are not taken over for a repeat order. If you want to pass your own custom fields you have to develop your own function.
If you mean “custom options” = “product options” added by a product add-on plugin like “WooCommerce Product Add-Ons”? We have tested the two popular plugins “WooCommerce Product Add-Ons (Link: https://woocommerce.com/products/product-add-ons/)” and the YITH plugin “YITH WooCommerce Advanced Product Options (Free & Premium, Link: https://yithemes.com/themes/plugins/yith-woocommerce-product-add-ons/)”. With these plugins, the fields are transferred when a new order is placed. It is important, that we do not receive any financial compensation for the reference to another page or product.
I hope we could help you and I am looking forward to your feedback.
Best regards, Poly-res Team
