Hello,
WooCommerce released High-Performance Order Storage (HPOS) in version 8.2 (October 2023).
As of April 2024, Meta Box is not compatible with HPOS, which makes added custom fields not shown in WooCommerce but also "related plugins" like Woo Susbcriptions (previously WooCommerce Subscriptions).
At this point, we've disabled HPOS. That being said, WooCommerce is going forward with HPOS.
I would like to know if you plan on supporting the "feature" anytime soon. Is there a roadmap?
Thank you!
