Why Won't My Facebook Update | New 2019

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

Edit: this seems to be a concern that Facebook know. It's a problem with the Facebook application, and not a generalised Play Store concern.

This is what worked for me a minimum of.

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

  2. Settings > Applications > All > Google Play Provider > Manage space, Clear all information and Clear cache


It doesn't hurt if you restart your phone before you try upgrading facebook once again. As well as, the mount was SLOW. Just a minimum of 4-5 minutes. However, it did work. If not attempt to uninstall it, or just wait for a repair.
