Hi @Montana-Verde0
Most of the time, error happens when the Airbnb Profile Name doesn't exactly match the Bank Info Name, based on my experience.
Ex.
1. Name on profile is for an individual but bank info is a joint account, different Bank account name and vice versa.
2. Incomplete Airbnb name compared to bank info name indicated.
Others:
1. Incorrect Billing address
2. Incorrect bank code or swift code
