Just as an idea as I havent tried 1.3.7 beta yet - and not sure if possible and or if you have tried. But have you tried creating the query loop and then using the loop in the related post element? I believe the related post has the relationship query (again not sure if it is possible, but this would be something I would look at).
Yup does not work for me. I see this as critical for my application. I have no idea where to place the PHP. So I cannot test that, a nod on this would be helpful. Otherwise, the only workaround I can see is to create hundreds of ACF post types which would mess up my dashboard somewhat, although I have other issues with ACF. Another alternative is to use a URL /beauty_cat/health-club/
Use Child of: {archive_title} in the query loop. Then it grabs the archive title that the user is currently viewing and shows only posts in the category in the loop.
