Posting this in the hope that the Airbnb system developers pick up on a hole that needs fixed in the system, that has been ongoing since split payment was put in place and is still a problem. I booked a property last year for a trip for my son and I, on the split payment basis. My card expired early and I received a notice from Airbnb telling me that the second payment had failed (due to expired credit card) I immeadiately went to my account and updated my new credit card details and also informed the host of the problem. I wrongly assumed my new card would be debited. This evening, one week before booking my reservation was cancelled, as the second payment was tried again from the expired card. I spoke to Airbnb and the gentleman asked me to raise this issue as he would and had on 2 previous occasions. I immeadiately re-booked for the same dates on the same terms, but a the host had a strict cancellation policy I am out of pocket of £170 till the host agrees to refund. I am sure the host will refund, but this is not an issue I want my guests to encounter. Please can the developers either issue clear instructions of how to activate a new card on the account that will be associated with an original booking or change the system so that it is automatic? This issue is a recurring and old problem that need fixed. Cheers Angela
