Hello,
With the instructions that we gave you, all other players that have the same issue with the facebook connect resolved the problem. The issue happens with you have an "invalid" facebook token, meaning that you use a different facebook login. That's the reason that we always recommend to fully delete both applications and removed from settings any facebook account linked and start fresh, by reinstalling both applications (so the game will ask you again facebook permissions and you will use the correct account).
If this doesn't work again, please contact as a
support@frozenshard.com with an screenshot of exactly what happens on the login screen.
Regards,
