I received the following message from ABB today after their deadline to the guest to update her payment info passed--
"Please be advised that even though your guest has not successfully completed their full payment, Airbnb has issued the remaining payout to you for $285.47, it may take up to 3-5 business days for the funds to be available on your account.
Hope this helps.
Payment problems are rare, but when they do occur, we do our best to assist the guest with correcting the issue, while keeping the host informed. If you are ever notified of a payment problem, please feel free to ask us to cancel the reservation at any time without penalty to you.
We have contacted your guest with instructions on how to complete the payment to Airbnb. With the cooperation of your guest, we can work to collect the balance so everything can continue as scheduled."
I am super appreciative for the response and thankful to @Nick for routing the issue.
