Actually there are two places for Settings -
Note that here in comunity ( where you made this post) up in the upper right you will see a little circle representing YOU that you can clcik on and one of the menu items is MY Settings
These settings apply to the Community.
HOWEVER - in the main area of FamilySearch (outisde of the community portion)
you will ALSO find in the upper right hand corner - with your user name that you can click on and see a menu item for settings.
The Commuinity and the Main area of FS - are really two different systems that have been made to link to each other. Each one has its own account settings options
see screen shot below. (for the main area of FS)
