[reynaldichernando]

WARN new NativeEventEmitter() was called with a non-null argument without the required addListener method.
WARN new NativeEventEmitter() was called with a non-null argument without the required removeListeners method.

Is this a breaking change or just a warning? I'm trying to figure out why voice is not working.

Edit for reference: not a breaking change that I could see, voice still worked despite the warning
