Does not work? Perhaps lack of standardization between the US and Europe?

Going to Europe soon so i downloaded my official « Digital Covid-19 Vaccine Record. When scanning i got a beep with an error msg of « error at position « 0 » or something similar. Disappointing

Gives wrong readings

For some reason when using this app on iPhone, it rejects certificates that should pass. When using the app on android, it works fine.

Doesn’t work

I’ve been double vaccinated in Luxembourg and have the certificate in paper form; still, upon scanning the QR code, this app shows “unknown code” for 5 criteria. The only criteria it gets right is my name, DOB, and vaccination date. Unless I’m missing something, that makes this app pretty useless.
