I'm trying to get prev/next entry using positionedAfter and positionedBefore filters but getting weird order on results because order('postDate desc') seems to be ignored.
{% set prevSibling = craft.entries.positionedAfter(entry).order('postDate desc').first() %}
{% set nextSibling = craft.entries.positionedBefore(entry).order('postDate desc').first() %}
Can anyone help?
