Hey MrRalphMan, thanks for reaching out! We understand how exciting the legendary world of VR can be and wanting to share the experience with our loved ones; however, some experiences do disable some of your Quest's screen sharing features while you are using the app. You can always verify whether or not this feature is disabled by pulling up the universal menu and checking the Sharing panel to see which screen sharing features are allowed for each VR experience.
Our voice command feature is currently only available to people using Oculus in the United States with English set as the default language. We'd be more than happy to get you pointed in the right direction to share your feedback regarding global support for voice commands; you can send your thoughts over to our UserVoice channel here!
