There are a couple of way to enter your referrer's code onto your account. Make sure to add a referral code within the 48 hours of creating an account. After the 48 hours has passed, you will no longer be able to enter a referral code. You can enter your referrer's code by entering their referral code when you create an account.
Please keep in mind that if you went through your referrer's link, you will not be given the option to enter a referral code. When you sign-up through a referral link, it immediately automates their referral code into your account. So if you don't see this option, but you went through a referral link, don't panic because you did all the right steps!
Another way to enter your referrer's code is by tapping the three lines on your app and clicking "Add Referral Code." This will redirect you to the page where you add the referral code.
Also, you may add a referrer's code by taping on the Refer tab.
*Please Note: After 48 hours of creating your account, these features will no longer be available. Unfortunately, there will be no way to add a referral code after this timeframe has passed.
