Answer 1

Yes, it's depreciated. The fix it quite simple, just move the code...

From onTokenRefresh() in your FirebaseInstanceIdService subclass

To onNewToken() in your FirebaseMessagingService subclass

I would recommend making this small code change over using old versions of firebase. Probably a good idea to also migrate to AndroidX [https://developer.android.com/jetpack/androidx/migrate] while you're at it.
