Hi Michael - I've had something similar just now to be honest. Received a sms msg for a booking request, but when I go into my account - no message?? I can't respond to the sms either as it's an airbnb number. Frustrating! There must be something wrong, but it's not helping us get our bookings that's for sure. Good luck with your issue though, do you know the email fro support? Airbnb are usually so good with their technical stuff, rarely a problem, but when there is a problem, it's frustrating that all the help is automated questions which actulaly don't help when it's something quite specific whcih doesn't happen often.
