problem linking Facebook

Hello, your app seems to be exactly what I am looking for. I was previously using Publicize from Jetpack but stopped for a couple of reasons. 1. It stopped pulling my featured image and 2. I want the ability to post to multiple platforms like Pinterest and Instagram in addition to Facebook.
I found your plugin and installed it, everything is great. I understand that I will need the Pro version to post to some sites, and I am ok with purchasing it. However, I wanted to try it out first on Facebook to see how it worked. And it doesn’t.
I added my Facebook account and put in the App Id which I got from FB, and also App Secret, which I guessed was my FB password. I clicked Authorize your Facebook Account and went through those steps. I got a green box that said: Auth Info. This is normal technical authorization info that will disappear unless you get some errors. Now Facebook is showing up as a linked account but it says this:
Auto-publish to Facebook (Facebook #0) Attention required. Unfinished setup ==> [Show Settings] [Remove]

Can you please advise me how to finish the setup?
thanks,
Lisa Anderson
