Facebook Page Plugin (Jetpack)

Hi, I am using in the bottom footer the WP Facebook jetpack live widget to show our daily Facebook posting on ten of our websites. For the past six months this has all been working fine and been perfect for our requirements. All of a sudden the Facebook posting has disappeared from displaying ONLY on the mobile phone version, which is probably more crucial than the desktop display. I have tried deleting widget, then re installing, clearing cache etc, but cannot get FB posting to display on the phone. I don’t really want to use a plug in as the widget has been perfect for our needs, but just need to get this to display again on the mobile phone version. Any help would be greatly appreciated.
