Country code in IP Access Rules

Hi, I can’t use Country code or Country name in IP Access Rules.
Cloudflare docs show that we can use country code for blocking but when I add blocking rule by country code or country name nothing happens.

You can only block by country with the IP Access tool if you are on an Enterprise plan. From the document you linked to:

IP Access Rule limits

Accounts are limited to a maximum of 50,000 rules. Enterprise customers can request increased rule limits via their Account Team. Block by country is only available on the Enterprise plan

However, you can block by country on any plan level with Firewall Rules.
