Can't Block Entire Continents using Firewall

Hi Cloudflare folks
I have the Pro plan. I need to basically block several countries using Firewall rules. My client doesn’t do any business outside the United States. Everything works fine when I create a rule for individual countries using the OR expression.

I would like to just block entire Continents like Asia, Africa, and South America. Maybe Antartica (Lots of spam from the ice). When I setup the rule to block a continent I get the following error in RED

“not entitled to use advanced Geo IPs in expression, at index: 0”

Can anyone help me or answer why I’m getting the error?
Thank you!

This doesn’t help at all. I’m suppose to have support and access to creating rules for the firewall.

Why was this post response in anyway helpful?
