Describe the bug

1. I registered a test via QR-code, successfully.
2. for 36hrs, I received the message "Ergebnis liegt noch nicht vor" when pressing the "aktualisieren" button in the app
3. I became impatient, and removed the test (hoping that re-registering it would finally give me a result)
4. I scanned the QR-code again, on the same mobile device.
5. I received "Fehler: Der QR-Code ist ungültig oder wurde bereits auf einem Smartphone registriert".

Expected behaviour

in step 5 above I can register the test again, as I'm the rightful owner of the QR-code

Steps to reproduce the issue

see above

Technical details

• iOS Version: 14
• Device: iPhone 11 Pro

Possible Fix

most likely a server issue?

Additional context

Yes I know, people shouldn't be impatient when waiting for test results, but the tester (at CGN-airport) told me that results should be available after 24hrs...

This Issue was already rased before.
It is not possible to have a test result registered 2 times.
See this statement from @thomasaugsten:

Hi unfortunately this is not possible. We have to ensure only one phone can scan the qr code and submit his diagnoses keys. We are not allowed to save an ID of the phone this is the reason why the qr code is only valid for one scan.
Please wait for the normal way (a letter via post mail or Gesundheitsamt calls you) of the test lab to get your result.

One question:
Did you see this warning? Because this makes 100% clear that you can add the QR-Code again.

[gernotstarke]

Thanx @Ein-Tim , but that is imho not user-friendly. I read the appropriate sentence in the FAQ, but that does not solve the problem... There will be NO letter from "Gesundheitsamt" in case of negative test results.

Speed of results-delivery should be a high-priority goal... and printed letters are not known for their "runtime performance".

And, as discussed in the thread (@thomasaugsten ), usability should be improved to at least warn (impatient) users like myself that they are about to invalidate their QR-code.

Regarding to your question: No, I did NOT get any warning dialog/message, test was immediately removed when I hit the button. Cannot create screenshot, though...

[gernotstarke]

I really appreciate your immediate response! Shall I close the issue, or will you close it?

[Ein-Tim]

Please leave it open for a bit (just btw I'm not a dev so I can't close it)...
@thomasaugsten Why didn't @gernotstarke see a Message during removing the test? Can you confirm the Message is still there in 1.3.0?

@gernotstarke Which CWA Version are you using?

[gernotstarke]

I'm using 1.3.0 (6)

[Ein-Tim]

Okay, so if the warning wasn't removed (which would not make sense) than you should have seen it... Please clarify @thomasaugsten

[gernotstarke]

obviously I cannot double-check it with my own code. In case you can provide a test-qr-code (here or by DM), I will try to reproduce.

[thomasaugsten]

The message is still in the app.

You can check this by your own when you generate a qr code with the content:
test?_randomnumber_

[gernotstarke]

thanx. I must have been very impatient to overlook that message.

@thomasaugsten the QR codes with test?randomnumber don't seem to work anymore in CWA 1.5 is this correct? Is there another way to generate QR codes for test purposes?
