Android Facebook App Not Working | Update

Got this myself on my phone, and it simply rejected to update. Here's what worked for me.

Edit: this seems to be a concern that Facebook recognize. It's a concern with the Facebook app, and not a generalised Play Shop issue.

This is what benefited me at the very least.

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

  2. Settings > Apps > All > Google Play Provider > Manage room, Clear all data and Clear cache


It does not hurt if you reactivate your phone prior to you attempt upgrading facebook once more. And also, the set up was SLOW. Simply at least 4-5 minutes. But, it did work. Otherwise attempt to uninstall it, or just wait on a solution.
