We are in the same boat for Placer/Nevada. Both counties tax people have been really helpful and trying to help us find a workaround, which is great, but also ridiculous since its airbnbs mistake. Airbnb has had TERRIBLE service for this issue and refused to tell us how much they paid the wrong county. They must have realized they were paying the wrong county since they stoped collecting the TOT at all and never told us.
Im curious if anyone had had luck with small claims court or if that's even an option since we all probably signed some arbitration clause with them
