Airbnb can withhold funds without informing you for a number of reasons:
Claim / resolution payments.
Alterations to bookings.
Partial payment bookings.
Full amount not collected from guest.
If Airbnb cannot collect the full amount (yes even $1 short) this will result in a hold on the payout, and you will not receive a notification about it. In fact until you go 'digging' you will not even realize that you are out of pocket!
