Messenger Service Demo always fails ignoring service installed first

Issue description

The demo states the MessengerService app must be installed BEFORE the MessengerClient. On a fresh install of VS22, I can build and deploy the MessengerService and start it but upon deploying the MessengerClient and launching it I am always met with "The MessengerService app must be installed BEFORE this application. Please uninstall this app, install MessengerService, and then reinstall the MessengerClient app." I'm trying this on clean updated GooglePixel5 devices.

Steps to reproduce the issue

1. Build the sample project and deploy the MessengerService
2. either launch or don't launch the MessengerService on the device both results the same
3. deploy the MessengerClient and launch on the device

What's the expected result?

The example of the demo where the client talks to the service

What's the actual result?

"The MessengerService app must be installed BEFORE this application. Please uninstall this app, install MessengerService, and then reinstall the MessengerClient app."
