Open the app and log in to your account. On the first screen, please select the person icon
You will then see a list. Please select 'Change Username' from the options:
Choose your new username, and type it into the field and make a note of what you have chosen. Please, do not use any special characters such as >< etc , as the system will not recognise them. Also please note that your username will be case sensitive for logging in in the future. Once you are happy with your username, select submit.
The submit button will log you out of the app, and you will have to log back in again, using your new username you have just created. On the home screen of the app, you will get a message displaying 'Your details have been saved'. This confirms you have changed your username
From here, click on 'Get started', and log back in using your new username. Your password will not have changed.
