The "Premium" Support Line is 1 six 4 7, nine 4 five, nine 6 two 7 call them to report the problem. It is wide spread and has never been addressed let alone fixed. From what I know it happens all the time, the IT is contracted out to another provider, so not addressed by Air Bnb directly. But it needs to be rerported in large number so something can be done. Get them to take a screen shot and have it sent to IT along iwth your account info.
This glitch makes the Instant Book features simply dangerous, so I never use it as dble bookings will occur. As preimium placecment is given to those who opt for the Instant Book feature, it's also unfair.
Being out of cell range also makes the risk of losing host status higher as one cannot respond to Booking Requests on itme, even if its only to Decline ( another strike against the host) for unbookable dates made available in error.
I call many times, no resolution, no hope, no help.
Thoroughty unimpressd withAir Bnb for launching an unreliable platform, which is essentially all they offer. If they cant get that right, what point is there?
