Research direction
Start by reproducing the reported 0.79.0 behavior using the Swift sendEvent call and the JavaScript NativeEvents listener on both iOS and Android. The report provides no usable repository link or file path, so trace the native event and listener entry points from there. Done means the event is delivered on both platforms without the no-listeners warning.
