Sorry I never got back to this, it's difficult for me to sift through the posts on this forum to find Clay.io related issues. We do have our own community now
, so that's a good place for things like this.
As for the issue, are you still having the same problem? Does a Facebook window not open when you click the Facebook icon? It's probably best to respond to this via my email firstname.lastname@example.org or make a post on the community
