We use module PreOrder version 1.0.9 for my Magento 2.2.

However, there is an issue that I notice that when all the child products are pre-order, parent product doesn't show the Pre-Order button.

If there any way to fix this error? 


To fix this error, please edit files as below:

+ app/code/Bss/CustomizePreOrder/Helper/ProductData.php

  • + app/code/Bss/CustomizePreOrder/Plugin/CategoryCheck.php

Or download the attached files below and overwrite the current files on your site.
