Terrible, God awful buggy mess. I have no idea what has happened during the last couple updates, but the "quality" of the app has been degraded SIGNIFICANTLY, as if the bar wasn't low enough already. Terrible jittering while scrolling through my feed, notifications won't update for days, if at all, and Messenger has been acting funky since the last update, too. I don't know what's going on but somebody over there in QC needs to get their act straight and fix this broken POS.
