That's great but we've been asking for this for 2 years now. It seems like this won't be implemented anytime soon, and we have to use ACF in order to use custom fields with Woo. Here is the original thread where the issue was raised and sadly ignored: https://support.metabox.io/topic/woocommerce-high-performance-order-storage-hpos-support-and-compatibility/
Hi Harry, if you can't wait, ACF Pro now has this capability since start of April:

For those looking for this functionality, it seems like ACF pro will be implementing soon. Hopefully MB won't be too far behind:
ACF Support for WooCommerce high-performance order storage (HPOS).
Hi, can we get an update on this? I have a similar situation going on and wondering if there is a work around we can use in the meantime until this gets fixed.
