I’m trying to figure out how to sign in to facebook through wp admin. I’m getting a warning that I need to to submit my app for review, but I cant find any info on what to select. It also asks me to make a screencast of what the user sees, which seems a bit unneccesary since I am the only one who needs to sign in to set up the app.

Some sort of clarification would be nice, as well as a more verbose error message in wp-admin (when pressing OK and logging in to facebook, the button to continue in wp-admin becomes unresponsive, as mentioned in other threads) .
