Android device does not connect to firebase DebugView

I'm trying to connect the device to DebugView. but, do not connected.

I referenced the DebugView document.

All I know is what is stated in this document.

Is there any other reason not to connect?

I simulated the following.

1. Open the terminal. and entered a command.
2. adb devices
3. adb shell setprop debug.firebase.analytics.app com.example.myapp
4. start the app(com.example.myapp).
5. Check [Firebase -> Analytics -> DebugVIew]

If my question is not clear, talk to me please.

Looks like there is a problem with Firebase DebugView. It doesn't work on me either.
