You can update your profile with your personal information in the app. From the Dashboard, you can tap on the profile image, or by tapping on the top right menu, and choose "Profile".
Check that your name and mobile phone number is correct. If not, correct it and Save.
If you haven't set a profile image, you can do so by tapping on the image in the profile. You will then be asked if you would like to take a photo with your mobile phone, or if you would like to choose an existing photo from your phone.
