each time I go to play a game I try to send lives. then I click to send lives to friends. Following that recently I keep getting a pop up asking me to sign into Facebook to continue. I can't do this because I am already signed in. I checked and both Apps are up to date and the connection to Candy Crush saga is up to date on Facebook settings. What am I missing? Thx for your help in advance. I am needing step by step instructions because I am not tech savvy. (Also I never receive any lives. )
