Facebook / Twitter Feed

Assistance required please.
I don’t go to Twitter every day and obviously not checked my own posts on there for a while.
My Joysofglass page Facebook page is linked to my @Joysofglass Twitter account and is set so that everything I post here is also posted on Twitter.
Well it used to be but for the last several weeks it has not been auto-posting to Twitter if I directly load a photo. It does post if I share a link / photo or only put text.

There is no doubt it is not auto-tweeting posts with photos, I’ve just tested it.
Facebook post + photto = no Tweet.
Facebook post text only = Tweet.

I think it is auto-posting those with a video but then it only tweets the text, not the video which makes the tweets look really stupid !!
Was it something I said ?
