Cannot request QR code for already existing negative test certificate

[LJPLux]

Technical details

• Device name: OnePlus 6T
• Android version: 10
• App version: 2.17.2

Describe the bug

I did a test and received a negative result which got emailed to me by PDF. It contained a QR code for the CoronaWarnApp, not an EU QR code.

When opening the PDF in the CoronaWarnApp, the app asks whether to import the certificate. I clicked Yes.
Then it asked to create a EU QR code, I hastily pressed No.

This proved to be an undoable error.
After realizing, I tried reimporting, which worked, only to tell me the QR is invalid or has already been imported.

I now have a negative test result in the CWA app, which doesn't allow me to request a QR code.
It tells me that there is a link 'specified above' to get an EU QR code, but there isn't (see image)

Any help in preventing such an error in the feature is appreciated.

@LJPLux Thanks for the report. For the moment I would consider this an enhancement request of the following: It should be possible to request a EU DCC, even if a user did not request it when registering the test.

Best wishes, DS

I just got a reply from the SAP CWA OS team:

Das ist korrekt. Mit der Ablehnung bei der Frage nach dem EU-Zertifikat werden bei der ausgebenden Stelle (im Testzentrum bzw. beim Integrator der Labore bereits die "Weichen gestellt". Damit wird nach der Evaluierung des Testergebnisses entweder der Datensatz für das Zertifikat erzeugt und verschlüsselt - oder eben nicht.

Nachträglich erneut ein Zertifikat anzufordern, ist in dem Prozess nicht vorgesehen, tut mir leid.

So it seems this is indeed a systemic feature. Why would anyone NOT want a EU-DCC issued to them?
One fat finger and your test is useless.

One fat finger and your test is useless.

Exactly that is my problem, which I also described in the above linked issue.
