As if this was not all messed up already, 🇩🇪 Corona-Warn-App v 2.6.1 has messed this up even more

For those vaccinated in 🏴󠁧󠁢󠁥󠁮󠁧󠁿🏴󠁧󠁢󠁷󠁬󠁳󠁿 and Northern Ireland travelling to 🇩🇪 read 🧵

This comes thanks to a discussion with @legumjus
@i_x_s, and a tweet from @hodadr

The prerequisites: letter from NHS 🏴󠁧󠁢󠁥󠁮󠁧󠁿🏴󠁧󠁢󠁷󠁬󠁳󠁿 or Northern Ireland confirming vaccination status, with QR code on it, and Corona-Warn-App latest version (2.6.1 on iOS)

Up until today's new Corona-Warn-App update, if you imported a NHS QR code into the app it just displayed it, and did not do any validation

For that you needed the *separate* CovPassCheck App (which is only in 🇩🇪 app stores - bit of a pain, but I diverge)

But NOW the Corona-Warn-App allows you to verify the certificate... and it shows VALID ✅ - UK NHS QR code, set to check validity in Germany

But if you check it in CovPassCheck you get INVALID ❌

So I have the same certificate that is showing as valid in Corona-Warn-App, and showing as invalid in CovPassCheck 🤬

The answer - sadly - is that CovPassCheck is correct and it is INVALID, as per this tweet

Plus de facto a venue you would enter would use CovPassCheck for this process, not Corona-Warn...

So the rule for Germany is *still* that NHS QR codes do not have full validity in Germany, whatever the Corona-Warn-App says

Sorry

(and jeez, can't people get the comms right so I stop having to explain this shit?)
