Hi @Isabel_Torgal
We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.🤗
Most likely, you are logged in with a Kingdom account on iPhone so you can't find Facebook friends there.
Right now, I'm asking you to check the steps below. Check App Update > Log Out Game > Restart Device > Open Game & Log In.
Let me know 😊
