Hi and Welcome to our Community
In F5 cannt sent or receipt lives from friends . If Facebook is disconnected from the game and you have it connected to your King account, then the Lives will automatically go through there.
Check also this page with Lives issues.
Welcome to the friendly King Community.
Since your sister is not playing the game through Facebook connected, she is playing the game through Kingdom account. In that case if you want to exchange live with your sister then you also need to sync the game with Kingdom account and connect the game through Kingdom. This process will not be possible if you are only playing the game via mobile, but if your sister syncs her game with Facebook, you can exchange lives with her.
Thanks!
