I have updated the robots.txt in our web app (digitalnz.org) to get twitter card working. It is working for one path but not other.
robots.txt
User-agent: Twitterbot
Disallow: *
Allow: /records/* (Working)
Allow: /user_sets/* (Not Working)
User-agent: *
Allow: /
Disallow: /records
Allow: /records/*
Allow: /user_sets/*
Crawl-delay: 1
In card validator i am getting this message for user_sets
