Describe the bug

Since yesterday the app stopped working completely. I tried to find a fix but I couldn’t. In this time there was no update neither the device or the app.
For further information please watch this video: https://drive.google.com/file/d/1D9AF0b2T1UWUuX2iGbfFhXCy1wkdgUOR/view?usp=drivesdk

Expected behaviour

Normal operation like before and on other devices.

Steps to reproduce the issue

That’s the question. I did nothing but it failed. Please ask if you have any guess.

Technical details

• iOS Version: 13.6.1
• Device: iPhone 8
• App: 1.2.1(0)

Possible Fix

Additional context

[Ein-Tim]

So you said you tried to fix it, could you please descrieb how you tried it? (so that I don't propose you to do things you've already done 😀)

[xander1401]

I did the possible fix from #911 and tried switching everything on and off. I didn’t reinstalled it because I don’t want to lose the data

[Ein-Tim]

So you also restarted your phone already? 😉

[xander1401]

Yes

[Ein-Tim]

Ok good, was "Risiko-Ermittlung" deactivated for more than 24h before this occured (switching off Bluetooth, activated Flight Mode, etc.)?

[xander1401]

No, everything was normal

[Ein-Tim]

You said it stoped working yesterday, but the App says the last update (download from keys) was on the 24.08.20, so it stoped Tuesday, this is very weird. Can you go into "Einstellungen->Datenschutz->Analyse&Verbesserung->Analysedaten" and see if there are files named "ENA"? You don't have to upload them, just say if there are any.

@thomasaugsten Any Idea what could have happend here?

[Ein-Tim]

Btw is "Background App Refresh" activated?

[xander1401]

There is no “ENA” file. Background App Refresh was off and is now on but I looked every day in the App since the release and it worked perfectly

[Ein-Tim]

Ok, so you now activated it, could you wait some time and see if this solves the problem, sometimes it does

[xander1401]

Thx. I will post the result tomorrow

[xander1401]

Ok, that was an easy fix. Started working again a minute ago. Great job!
