Hi Ana!
If you payouts are late, you need to contact Airbnb via telephone or Twitter. I have found that reaching out to them via Twitter has the fasest response time. Just mention that it has been well over 24 hours since your guest checked in and you still have not received your payout. Then they will ask you to send them a private message via Twitter with your reservation details. Always remember to not share any of your account details publicly.
Additionally, I highly recommend checking your payout methods and see if there are any discrepancies. Best of luck!
Warm wishes,
Judy
