Why has the Facebook app disappeared in the latest software upgrade?

[AC Question]

why has the facebook app disappeared in the latest software upgrade?

I accepted a software upgrade on my HTC one last night and since then I can't access Facebook as the app isn't installed. When I try to install it, it encounters an "unknown error"
