Describe the bug

Since more than 2 weeks, the screen shows "Risiko-Ermittlung war für 12 der letzten 14 Tage aktiv".
That's really implossible, because I've installed the App on it's launch day and never deactivated "Risiko-Ermittlung"
At night I activate flightmode & turn off Bluetooth.

Expected behaviour

The screen should show: "Risiko-Ermittlung dauerhaft aktiv".

Steps to reproduce the issue

--

Technical details

• iOS Version: 13.6
• Device: iPhone XR
• CWA-Version: 1.1.1 (3)

Possible Fix

No idea. Neither the update to iOS 13.6 nor the updates form the App fixed the problem...

Additional context

I'm not sure but I think the issue first occured under iOS 13.6 Public Beta 3. But now I'm on the offical version...

Internal Tracking ID: EXPOSUREAPP-1909

I've wrote an comment under https://github.com/corona-warn-app/cwa-app-ios/issues/804#issuecomment-652278062 3 weeks ago...

Same for me. I‘m at 10 of 14 days. I have the app since the release and never reached 14 days. That‘s ridiculous.

Thanks for reporting this in a separate issue. The reason is probably that the counter reduces the number of active days also if the exposure logging was switched off over night (e.g. by switching off the device). We are in continuous discussions with the product team and the RKI about the counter and how it can be changed (e.g. counting a day if exposure logging was active during the day, but only switched off over night). Moreover, some extensions to the status display are planned. We will get back to you as soon as we have news.

Thanks for the detailed explanation. It‘s just a bit weird that it‘s updating everyday, but the active days are not changing at all. At least that‘s a bit confusing. Hopefully this can be improved in the future.

That's actually the main misconception. Active Days and the updates are not the same. The active days refer to exposure logging, i.e., the sending and receiving of bluetooth beacons. Update refers to the risk analysis, i.e., downloading diagnosis keys and checking whether you had risky encounters. But as Sebastian said, we're working on making that clearer.

Transferred this issue to cwa-documentation as it affects both operating systems

I just heard from someone that their iOS App (1.1.2) is stuck at 10 of 14 days: https://twitter.com/JakobFekete/status/1289547379255808000

They told me that they have their device on "airplane mode" from time to time.
Is "airplane mode" time subtracted from the 14 days under iOS (this seems not to be the case for Android)? That could explain, why it counted up to 10, but got stuck from then on.

[tkowark]

Yes, airplane mode on iOS deactivates Bluetooth, and accordingly the ENF. This time is deducted from the "active days".

[Ein-Tim]

New observation:
2 days ago my active days went down to 11, then yesterday went back up to 12 and today they went back to 11...

[Ein-Tim]

Now the App shows "Risiko Ermittlung dauerhaft aktiv" 👍
@danidoedel What about you?

[danidoedel]

Yep I can confirm, it seems to work as expected. Even if it's hard to figure out what the expected behavior is 😁

[Ein-Tim]

Closed this because for us two the issue has been solved.
