Can I still add a refer code after registering an account?

Yes. You may add a referral code after registering a new account using the Fluz app's self movement feature. 

However, note that the self movement feature only works if you do not have any invites or downline under you yet. Once you have invited someone already, the self movement function is not valid anymore. 

Here's what you need to do: 

1. Press the menu button (☰),
2. There will be a red button that says enter referral code on the top right.  The button will only be there if this feature is still valid for your account. Otherwise, you cannot move yourself under a referrer anymore.
3. Then enter your referrer's referral code. 
   • if the referral link is http://joinfluz.app.link/EXAMPLE001, you only need to input "EXAMPLE001"
4. Once succesful, you will immediately receive 3 vouchers for up to 35% cashback.
