Downloaded it fine and eventually got it working - though hard to understand half of it as it's not in English (even with English set as the language). I've submitted my vaccination into it twice, yet still doesn't show anything and says I'm unvaccinated. Also got my negative pcr results from on arrival, and doesn't show any results in app. Hoping this isn't actually used much in places or I'm gonna have to keep showing extra paperwork everywhere and saying that the app doesn't work...
