Facebook service unavailable?

I've been having trouble downloading my library content to Facebook through the game, it tells me that the service is unavailable. I came across your comment in this thread and clicked the link you provided. There is an option on the site to download a mobile app for the sims 4 gallery. I downloaded the app, and logged in fine, but I'm still having trouble downloading to Facebook. when I try to click the Facebook icon it tells me that I need to download the Facebook app. I already had the app, but for the sake of curiosity, I deleted the app and upon being prompted from "The Sims 4 Gallery" app I re-downloaded the Facebook app. Unfortunately I'm still having trouble uploading content to the sims while attempting the mobile route.
