I am using WooCommerce Product Add-ons version 1.1.1
It all works fine however if the user has completed an Order and wishes to order the same again by clicking on the "Order Again" button, the product and qty comes over fine, but any Product Add-Ons selected are lost.
I am using WooCommerce 126.96.36.199 which I cannot automatically update to the latest. I can apply any PHP code changes required to fix this problem.
Please if anyone has found a solution I would appreciate any guidance.
