Hi.. can someone here tell me, why do I get an error like this :

Topic sync or token retrieval failed:
Topic sync or token retrieval failed on hard failure exceptions: PHONE_REGISTRATION_ERROR. Won't retry the operation.
I have a test with a real device and an emulator, the FCM emulator works fine and gets a token.
But on my original device, I got that error.
