The app will deliver you the right information at the right time, based on when you are having your treatment. Therefore it's important that we know your treatment date.
To change this date, you can update the date listed in the app, by visiting the More page, entering your Profile, and tapping the edit symbol next to ‘Operation date’. If there is no option to edit, then your care provider will do this for you (note that there can sometimes be a delay).
