Guys, can we just stick to the topic, please..
Also, the game follows FIFA and confederations' rules, UEFA still use the term "Czech Republic" (Yeah I admit that Slovakia, in the case in beauty pageants use the term Slovak Republic. But it's still Slovakia). Czechia was never used in any of the matches in either UEFA or FIFA yet.
Eswatini is now already used, but different code - https://www.youtube.com/watch?v=cePe1z1SyKo
I'm not pretty sure about Macedonia tho, since I watched recent matches and they still use Macedonia.
