Autoblog doesn't work with iframes, even with required addons enabled

I'm having an issue with iFrames are being completely stripped from imported feeds. The feed shows the iframes in it but when imported/processed by Autoblog they do not appear.

I've have the following addons enabled:
Allow Force Feed
Disable Sanitization

I have also 'enabled' them in the feed's options and have also tried recreating the feed. We're running the latest version of WP and latest version of Autoblog (v4.1).

I can provide a link to the feed via PM - don't wish to publish it as its a backend publishing pull into our main network site.

Edit: I've also checked out and tried: https://premium.wpmudev.org/forums/topic/sanitization-autoblog-doesnt-seem-to-work-as-iframes but still not working.
