Facebook removed that feature. The effect of this was that people had to create content within facebook instead of outside it. This reoriented the flow of content creation so that it must originate inside of Facebook, removing the ability to use FB as a passive consumer of content created in a workflow where the creators chose the entire flow.
IMHO this is one of the biggest steps down ever in FB history. It was one of the biggest attacks on the open web, and I'm sad to say that it mostly worked, and the internet at large is worse as a result.
