"Receive push notifications" and "Allow device attestation" toggles are greyed out

[UnlimitedCookies]

Both services seem to be broken and FCM shows disconnected state. I cannot toggle them off and microg doesn't give me a proper error message. Also, microg self-check shows that everything is fine.

No idea how to reproduce, but everything used to work perfectly.

Okay, after a restart the connection to FCM could be reestablished, but the toggles remain petrified.

From the log excerpt it looks as if device registration is disabled.

Correct, google device registration is disabled. Does that have to be enabled, because both FCM and Safetynet seemed to work with it being turned off.

Yes, it says right in the Cloud Messaging settings page that device registration must be enabled for that service to work.

If the device does not register to Google push servers, they do not know where to send the messages from your apps.

Then the bug lies in me being able to sometimes use FCM without having my device registered.

1. Why did this even work?
2. Should the FCM settings page enforce the activation of device registration?
