Hello there,
Yes, this has happened to me this week. A payment was made (apparently) by AirBNB on Oct 2 but it still isn't in my account as of the afternoon of Oct 4. For years now, a payment made by AirBNB in the morning would be in my account by 1pm on the same day at the latest.
My previous payment (made by AirBNB on Sept 30) got to my account the same day. Curiously, that payment is still showing as status 'Processing' on AirBNB. The payment prior to that (made Sept 27) also hit my account the same day, as did all the ones prior to that. The Sept 27 payment is no longer at status 'Processing'.
Before looking on these forums, I phoned AIrBNB Help to ask them what had happened. The person just stuck to the script and said 'It can take 9 days'. I had already explained that for years now, it has been received by my bank on the same day. I asked for a payment reference which he said he would send. It hasn't arrived. It is really frustrating that AirBNB Help knows nothing about this and won't look into it.
I am very concerned to read in this thread that payments are now taking over a week (it would be helpful if we all could specify whether we mean business days or calendar days in our responses).
