"Risiko-Ermittlung nicht möglich"

[zigel]

Ich habe CWA am 15.06. installiert.
Heute ist 18.06.
Ich bekomme die Meldung
"Risiko-Ermittlung nicht möglich. Ihre Risiko-Ermittlung konnte seit mehr als 24 Stunden nicht aktualisiert werden. Letzte Risiko-Ermittlung: Niedriges Risiko. Aktualisiert 16. Juni, 09:14." Mit dem Button "Risiko-Ermittlung Einschalten".

Handy-Modell Huawei Mate 20 Pro.

likely duplicate of #637

Hi @zigel,

thank you very much for reporting this! We are currently investigating this issue and will come back to you as soon as possible. If you can provide us with additional details, it might help a lot to identify the root cause for this behavior:
Did you change your phone date & time setting recently, disable background activity for the Corona-Warn-App or change the battery optimization settings for the Corona-Warn-App?

As #637 is very much the same, I will update #637 and close this issue soon to avoid duplicates.

Thank you very much and best,
Marc

Hi @marcmuschko,

• i haven't changed date&time settings
• i changed optimzation policy for this app: marked it as "locked" or "safe from optimization", like described here: https://www.reddit.com/r/Huawei/comments/ccdtu4/what_does_this_lock_icon_mean/

and officially here:

@zigel thank your lots for providing these details! We have identified the cause for this error and a fix is currently in progress. I will update #637 as soon as this is solved.

Including the permission request for "disable battery optimization" by default is planned for discussion and a separate issue, but that will also need some time for development, tests and proper monitoring of impacts on battery duration and general behavior of the app. However this setting should not affect the mentioned error after our fix.

For now as #637 will be updated accordingly, I will close this issue to avoid duplicates.
Thank you again and best,
Marc
