The stupid set up will not accept todays correct answer.
It says unknown country when I put what I know is correct.
It goes by official short form names and the answer is their official short form name in English now.
Yesterday's answer was Finland, not Republic of Finland, even though both are perfectly correct names for the country.
Likewise, if you tried to put United Kingdom of Great Britain and Northern Ireland as an answer, that wouldn't be deemed correct because the accepted short form is United Kingdom.
It's definitely a flawed system, but I think they've probably got to do it that way when they're providing a drop down list of answers for people to choose from when they type in letters.
