Hi, I have been getting that "Refresh Tiles" error for months now and havent been able to play the game. Would you please be able to run me through the steps of backing my account and logging out of FB? I tried clearing cache it didnt work and I am not sure how to log out of FB without losing my game. I would be grateful for your help, thank you!Thank you my man!!
Clearing cache didn't fix it, but clearing ALL DATA and cache and logging back in (in my case, through facebook) fixed the issue.
(Remember if you do this to backup your account!!)
