Facebook Instant Articles URL Not Working

Your plugin tells me to use this url to link/verify my website with Facebook, to then be able to post instant articles

https://www.garfagnanadream.it/instant_articles

Aside from being an xml document (weird), facebook do not accept it at all

“The provided URL is not being accepted because the site has minimal readership, which violates the Instant Article Policies (https://developers.facebook.com/docs/instant-articles/policy/). Please provide a different URL.”
