How does Vio App Worker

corona warning app / cwa-app-android

Hello

I have a Samsung Galaxy A40 with Android 10 and I get this error:

Error CAUSE: 9002
Something went wrong.

The Exposure Notification
Franework must be active, check
your tracing status

For details, there is this here:

The error always occurs when I want to switch on the risk assessment and also when I bring the device back from standby if this app was last displayed ..

How do I check my tracing status to activate what's there?

I have now put that in with Bugs, because no other category seemed appropriate to me.
