There was an issue in past versions where if you have the facebook app installed and you try to share an image in Instagram, it will fail or show up and go away when you check Facebook. You can run both but as far as sharing images to facebook from the instagram, it doesnt work.
Youre more than welcome to verify that for me and us, I dont use the Facebook app so it doesnt bother me.
I'm able to post to facebook just fine
