HPOS compatibility
WM Widerrufsmanager works through WooCommerce interfaces and supports HPOS order views. The additional withdrawal column is intended for both classic order lists and HPOS.
Order number is not the same as order ID
HPOS does not automatically change the visible order number. If a custom order number plugin is used, the number visible to the customer may still differ from the internal WooCommerce ID.
PRO with custom order numbers
If required, use automatic detection or targeted meta-key mapping. Meta-key inspection and the mapping test can be used to check whether the customer-facing order number is found correctly.
