Facebook App Not Working after Update

Got this myself on my phone, and also it just declined to upgrade. Here's what worked for me.

Edit: this seems to be a concern that Facebook are aware of. It's a problem with the Facebook app, and not a generalised Play Store issue.

This is what worked for me at the very least.

  1. Settings > Apps > All > Google Play Shop, Clear information and also Clear cache

  2. Settings > Apps > All > Google Play Services > Manage area, Clear all data and Clear cache


It does not injured if you restart your phone prior to you attempt updating facebook once more. And also, the install was SLOW. Simply a minimum of 4-5 mins. But, it did work. If not try to uninstall it, or simply wait on a solution.
