I'm having the same problem. I've only rented my home twice before, but my recollection is that in the past I was sent a message on the day the guest checked in that my funds were being released. My guests checked in on Sept. 16 and out on Sept. 18, and so far no sign of payment from Airbnb. Nothing has arrived to my Paypal account, and Airbnb is showing it as future revenue.
Does Airbnb have a number I can call to find out about my money? I'm supposed to have the money now and I want it now, which doesn't seem unreasonable. I have more renters scheduled for three days, and I don't want to let them stay if I'm not going to get paid.
