Why didn't I receive my referral bonus?

Please check the Payment Details tab in your profile to see your payout history.

Referral bonuses are included in your weekly payout and are not a separate PayPal transaction. 

In the below example, the $9.32 Weekly Payout for November 25 includes the $0.92 referral bonus.

Also, keep in mind that referral bonuses are only earned on task payouts. So if you refer a friend that earned $20 in referral bonuses, you will not receive a referral bonus for that $20.

Finally, you may have reached the bonus limit. Referral bonuses are earned for the first 180 days or $100 in earnings (whichever comes first).
