I'm trying to access all the items that does not have Featured
in their category array. The GROQ code I use is
`*[_type == "post" && *[_type == "category" &&title != "Featured"][0]._id in categories[]._ref] {title, 'mainImage' : mainImage.asset->url, publishedAt, excerpt, slug, categories}[0...6]`
But I'm getting 6 posts including ones with Featured
category. What's going wrong here?
