The problem

Steps to reproduce

1. Install last test build
2. Install Signal app and login

What is the current behavior?

Signal informs you that Google Play Services are missing. So you have to allow the app to run in background. After few minutes, the notification appears in top bar.

When you go in microG > Google Cloud Message settings, the option is enabled but the status stay disabled.

What is the expected correct behavior?

Google Cloud Message should automatically connect when it is asked by an app.
