Oakham Fire Station Baby Shark Challenge

Firefighters from Oakham Station take on the Baby Shark Challenge #babysharkchallenge #babyshark

Posted by Leicestershire Fire and Rescue Service Oakham Station on Friday, August 24, 2018

Expected Result

To be able to view the preview of the embedded facebook video in the article

Actual Result

Only the hyperlink is shown in the article that takes the reader to the video.

Here is the link to an affected Instant Article that, when viewed using the Facebook mobile app, only shows the URL to the embedded video: https://emergency-services.news/?p=3030

I have also tried adding

to the article, but this only proved to prevent adverts from being loaded into the instant article when being viewed via the facebook mobile app
