I’ve hit this exact issue with media-heavy WebViews on older Android versions. Android 11’s stricter media session handling is what’s causing it. Try setting mixedContentMode='compatibility' and ditch the layerType='hardware' property - hardware acceleration messes with audio playback on Android 11. You might also want to downgrade react-native-webview temporarily to see if it’s a library issue. I found versions around 11.x worked better with Android 11 than some newer releases. When playback stops after a few seconds, it’s usually the system killing the media session. This should fix it.
