There is a couple of ways to enter your referrer's code to your account. You can enter your referrer's code by entering their referral code when you create an account, clicking the menu bar and selecting add referral code, or by clicking on the Refer tab and entering it there. You will have 48 hours to enter a referral code. After 48 hours have passed, you will no longer be able to enter a referral code.
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 automates their referral code into your account. If you don't see this option, but you're sure you went through a referral link, then the referral code has already been applied.
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.
