The AirPort Express is no longer showing up in the Home app for users on the latest iOS 11.4 beta, casting doubt that it will be updated to use as an AirPlay 2 target.
In the first iOS 11.4 beta release, users started to see their AirPort Express appear in the Home app alongside HomePods and Apple TVs, suggesting the router might be updated to support AirPlay 2. This functionality has now been removed in beta 2 of iOS 11.4.
AirPlay 2, which is included in iOS 11.4 beta software, will allow users stream music to multiple speakers simultaneously. Since speakers are configured in the Home app, the appearance of AirPort Express in beta one spurred speculation that the device, which currently supports the first-generation AirPlay protocol, would be getting upgraded to AirPlay 2 in the future.
Now that it has been removed in the latest beta, it is unclear what the future holds for the AirPort Express. It could either get an upgrade to work with AirPlay 2, or it could be relegated to support original AirPlay.
AirPlay 2 brings many new features including multi-room audio, increased throughput, and better reliability. Devices like the Apple TV and HomePod will be getting updates to support AirPlay 2 when it launches.
