You seem to know what you are talking about but the other guy skimmed a wiki article after a brief web search, so I’m not sure whom to trust.

All categories have at least one country. Here is the actual data: https://eci.ec.europa.eu/043/public/#/screen/home/allcountries

There are no countries in this bracket.

Do you have a source for this? People like to repeat this rumour but I’ve never found out where he promises anything like that.

Sure there are, they are just hard to find on the official stores. I use mini review (website or phone application). https://minireview.io/
