My husband fixed it for me and it works now here is what he did.
Go to facebook then go to settings, then click on apps and websites, then click on edit, then click to Turn off.
Then turn it back on. That is all he did and it works now.
I am playing the game on my IPad and I can no longer send lives or receive any. I have checked for updates and there are none. This has been going on for several days. I am signed in with FB and have tried signing out and back in with no success. My App is updated and on facebook. Please helpπ§
