Hello. Thank you for contacting the Toolset support.
Adding compatibility for HPOS is on our to-do list, but we have not done so yet, I'm afraid. We have internal ticket and I've raised your voice to that.

If you're still interested in using Toolset to display order details, WooCommerce has made available a backwards compatibility layer which can be accessed here:
