Facebook Update android Problems
Edit: this appears to be an issue that Facebook recognize. It's an issue with the Facebook app, and also not a generalised Play Shop issue.
This is what benefited me at the very least.
- Settings > Apps > All > Google Play Shop, Clear information and Clear cache
- Settings > Apps > All > Google Play Services > Manage area, Clear all data as well as Clear cache
It does not harmed if you restart your phone before you try upgrading facebook once again. And, the set up was SLOW. Just at the very least 4-5 minutes. But, it did work. Otherwise try to uninstall it, or simply wait on a solution.
