You can customize your referral code in app.
Make sure you have the latest version of the app.
On the Fluz app, press the "invite" icon, found at the bottom navigation bar.
Scroll down and you will see your referral code right beside the violet "Edit" button. Press this button to edit your code.
Type in your new referral code. Press "update".
Please note that codes are all in capital letters and that it's subject to availability. If the system does not accept it, it's probably taken. Try again.
Please keep in mind that your previous referral code, link and QR code will not work anymore. Users you have provided it to will not land in your network properly and it would be best to reach out to them again.
