Incompatible with Jetpack's shortcode embeds

This plugin only worked for me if I disabled the shortcode embeds module on Automattic’s Jetpack plugin. Otherwise it doesn’t do anything.

I mentioned it in the discussion forum but didn’t get a reply. Judging by the various unsolved threads there, I don’t think the author is maintaining this plugin anymore. Better to find an alternative which comes with some level of support or engagement.
