Re: Won't update Facebook app

I'm also having problems with every Facebook update on my wife's Moto G2. I finally got it installed this last time, but it took several attempts, even after removing the app then reinstalling from Google Play. I have zero interest in ever using Facebook, but she wants it, unfortunately.
