IOS Upgrade will not let me change user

Question

Upgraded iPhone to 11.0.2 will not let me change user. I log out of facebook, then logout of candy crush (player "A"). Then I login to player "B" on facebook yet candy crush takes me into player "A". I cannot get out of player "A" no matter how I am logged into Facebook. My kids play and we cannot get to their saved games, it's stuck on mine.

Here is an update: I have four facebook accounts and four candy crush games. Before the update (to IOS and to CC) I had to be logged into facebook to play (on the iphone). If not I was prompted for a username and password. This no longer happens. I am not logged into facebook and I'm still stuck on the same game. I have no way to change the user on iPhone IOS 11
