Help with adding Mexican RFC to Listing?

[Christopher1151]

Hi all.  I have a few listings in the US and I'm trying to add a listing in Mexico.  I have a CURP and an RFC and I'm trying to add the RFC to my account and cannot.  I have message Airbnb CS and they told me to do the following:

To update RFC, follow the steps below:
1. Go to your Account > Taxes
2. Scroll to your Taxpayer information section
3. Select Add tax info
4. Select Another country/region
5. Add your RFC for Mexico

When I select "Another country/region", I get this message and can do nothing: "Tax info is not available for your country
We’ll let you know when this feature becomes available in the country where you host. Learn more about supported countries."

I have tried the website, the ios app, the android app, and both airbnb.mx and airbnb.com.  CS has not responded since I told them that the step above were not working.  Anyone been able to find a fix?
