Can you confirm if this works with the latest rewrite of facet please? I seem to be encountering a few issues with Facet 3.8 and I wonder if this could be the reason metabox custom field facets do not appear to be indexing on the site since the upgrade.
I've re-checked the compatibility between Meta Box (5.3.9) and Facet (3.8) and they look working as well. Meta Box has its own JS code and does not relate to Facet jQuery dependency.
