Hi Brian,

You should see an "Action" button at the top of your profile, and if you click on the arrow you'll be able to edit your profile.

I've added a screenshot which might make it a bit clearer.

Hope that helps

Go to your profile page (click your picture icon at the top right and go into My Profile) and there is a blue tab that says "Actions." If you click that, it will say "edit my profile." :)
