@Erin-Busby0 I hope you are well.
You probably need to check in with the host you referred that they used the link you sent them to create their listing, and they hosted their first guest with a booking of at least $100 within the 90 day limit.
What information can you see about the host you referred in the "refer a host" tab on your airbnb menu tab?
It will show you referral payouts that have been released/pending, and invite links that have expired etc
