OK so long story short, I installed Nova Launcher to work with a theme I wanted. I created a button on the screen for my facebook app, which has never given me any issue before. I would click it, and it would take me to my feed. Now, when I click it it fires up "Facebook Home" which is super anoyying. I cant seem to deactivate it, it doesnt even show up as an app that installed on my phone. Every tutorial I found on how to deactivate it reffered to there being a "home" listed on my list of apps. There is nothing. I cant figure out why this is all of a sudden happening.
