Hi Michael,
I also need to remove the slug. I’m redesigning one page with Oxygen, so I decided to make a custom post type and ACF for products, which were in old version as pages. So because of SEO I would like to have same structure of slug http://www.page.xx/product. But when I use your code, slug is removed, but my Oxygen template isn’t applied anymore. Is there some advice please? Thanks.
Tomas
