I have been trying to complete my booking since last night, first on my phone where I kept recieving an error message saying the bankcan't confirm my card, although I recieved an email from airbnb saying it was confirmed & called my bank who also said everything was clear. I tried on Chrome and Safari but neither worked either, giving me the same message and also another error message saying the either Airbnb is undergoing maintenance or the connection server timed out. How do I fix this or find out if the website is actually undergoing maintenance, and for how long?
