Odd, Ok use the other way to get there from the full site (not the app). near the top right hand side of all the pages, there is a Quick links dropdown box. Click the name and then select the "edit options" title. It will take you to the edit option page, where you scroll down to the bottom and toggle the newsletter to off. Make sure to click save changes at the bottom after that.
