Air Bnb suddenly won't let me book

[Christine1173]

Hello everybody,

I'm trying to book accommodation for this weekend. I go to book and pay and I get the following message: 

We’ll be in touch soon

Someone from our team will follow up with you by email. You’ll be able use your Airbnb account as usual once we’ve reviewed your account.

What does this even mean? They don't even specify when someone will be in touch. Has anyone also experienced this and was it resolved easily? I've already verified everything on my profile. I've never had trouble booking through Air Bnb before. 

Thanks!

Christine
