Hi there, I am on the same search... My guest has been in my apartment already a week and no payment received. Contacted Help centre, Twitter help no progress. Guest provided confirmation of the payment to AirBnB, nothing happened. I have read today quite many interesting stories, even Forbes mentioned this issue - probably it is nothing new how to improve your cash flow.
Let me know if something works I would try it as well:-). For me is this first bad experience I am very disapointed.
