Sometimes Airbnb performs guest verification, in which a guest is asked to confirm their identity.
In this case, you won't be able to approve or decline the reservation in Guesty, because this is a unique Airbnb status relevant for the verification process.
When a guest is asked to verify their identity, a delay may happen between clicking "Approve" and the reservation actually being updated to "Confirmed".
If this happens, we recommend reaching out to the guest directly, and asking them if they have any pending items from Airbnb they need to complete.
