I Updated Facebook and now It Won't Work | Update

Got this myself on my phone, and also it just rejected to upgrade. Below's what benefited me.

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

This is what worked for me at the very least.

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

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


It doesn't injured if you restart your phone prior to you attempt upgrading facebook once more. And, the mount was SLOW. Just at the very least 4-5 mins. However, it did job. Otherwise try to uninstall it, or merely wait for a repair.
