One piece of advice in advance: fix two classic tips
Have you tried turning it off and on again? The old IT support meme has proven itself time and again in practice – depending on the error, probably also with the Corona warning app. If there are any problems when installing or running the app, we recommend trying the two troubleshooting classics before doing a large search for causes and solutions:
- Restart your smartphone / tablet.
- If that doesn’t help: Uninstall and reinstall the Corona Warning app. Use the official sources to download the Corona Warning app: Google Play Store or. Apple App Store.
Do not worry: If you uninstall the Corona Warning app and then reinstall it, the go collected contact logs are not lost. The lists are created by the operating system via the Exposure Notification API and can only be deleted separately in the device settings.
