World At War

Hi Pickles, 

Thank you for creating this topic!

It seems that the latest Facebook app update is at fault here. 

Here is a workaround for the Android users:

1. Enter FB App -> Log out from FB -> Tap on options (next to your name) and choose "Remove account from device"
2. Uninstall FB App
3. Log in to the game through FB browser without the FB app installed

On iOS devices, you can choose at login to use FB browser instead. 

Let me know if you are able to log into the account.
