Error when communicating with Google API(17): Nearby.EXPOSURE_NOTIFICATION_API is not available on this device

Describe the bug

I get the following error after the first welcome screens:

Cause: 3
Something went wrong.
Error when communicating with Google API(17)

The exception trace has the message:

Nearby.EXPOSURE_NOTIFICATION_API is not available on this device

This is on a Pixel 2, all up to date. Bluetooth is enabled.

I have play services version “20.21.15” and it shows me the same “17.3.0” version in the error code. I don’t know why it does this.

Friendly note, you can’t compile from source code and expect it to work. The Exposure API will not work and you will get exactly this error 3, Cause Google API 17.

It’s very important to state whether you installed from Play Store, Sideloaded or Compiled from Source. That makes a huge difference in the importance of the bug.

The reproducible build question is still entirely valid but not directly related to this problem. So you may want to close this issue here as a duplicate of corona-warn-app/cwa-documentation#257

I have installed it from Google Play , and it does NOT work. Very strange.
