Can't log in game thru FB

Recently I did a "Factory Reset" to my phone, so I reinstalled AL back in. My ID which online thru FB can do normal login as usual. After a long run until DC or I off the apps, I can't log in again. I mean, I can't tap the button "Login & Play". How can I fix this? I already did million times of uninstall, reinstall and patch download. It's getting annoyed.

Close the window where u see Login & play, a new window appears where u get couple of options to login, "login with E-mail" & "login with FB(or perhaps facebook) click on login with FB, that might get u logged in using ur fb acc.
Hope it helps.

You need to disable facebook app on your tablet or phone then clear data of AL app. open AL app and log in with FB.
