I currently have same situation. Received pay out confirmation on 26th. It's now 31st, and it's still "pending".
Now, we, unlike others, have always received payments from Airbnb on our account within 24 hours. I know, they say it will be a week, but it's never been more than 48 hrs to show up in the account, even on weekends. Ever. This is a first.
I contacted cs, and received prompt, friendly attention as usual, but so far, no explanation or action. They said it's been sent as per the notification of 26th, and it normally takes up to 7 days, and will show up by 2 June. It read like a canned reply. I don't think they even looked. End of discussion.
When it doesn't show up on 2nd of June, I'll have to open another ticket. They won't be able to use the 7 days excuse, so I'm probably going to have to endure the usual run around again, until someone explains it. But that still won't likely get the money into my account 🙄. That will probably be yet another fiasco.
We'll see.
