Hey Maria, I'm literally experiencing the same thing. It says the payment has been sent on the 29th of December and that I was supposed to receive it on the 5th of Jan, but nothing till now. It's the 8th here and I'm supposed to be receiving another payout but still nothing, so that's 2 late payouts. This has NEVER happened before and we urgently need the money. I've contacted the Superhost support but the guy passed me on to another person and they've been silent since.
And one more thing, I've seen a few Australian hosts complaining about the same thing today. I'm in Indonesia, so it makes me wonder if the issue has something to do with our region..
Do let us know once you've received your payout!
