For security and privacy reasons you may elect to obfuscate the Total Amount on opening of the app (e.g. if you regularly access the app in public spaces).
To turn this feature on, open up your Profile page (press the circle in the top-right of the home screen). Then simply scroll down to 'Hide balances on home' and turn the toggle 'on'.
Once complete all balance information on your home screen will be obfuscated and available for temporary revealing only from the home screen.
