There's no limit to how many people you can invite. What varies by campaign is how many rewards you can earn and how many invites you can have running at once. Check the Referrals tab to see how your campaign works.
You'll see the number of rewards available in the top left corner of the screen.
For example, if you see 5 rewards available, it means you can invite as many friends as you want - but you'll only get rewards for the first 5 who complete all the required steps.
If you're on the continuous campaign
There's no reward limit — you can keep earning as long as you keep referring. 🔁
Instead, you refer one friend at a time. Your code is single-use, and once a referral completes, a new code may become available for the next friend. We'll notify you in the app and by email whenever one appears.
