Other changes in iOS 11.3 beta 2
Other changes not mentioned in the video include:
Siri control of AirPlay 2 isn’t enabled in iOS 11.3 beta 2 and earlier.
Last but not least, Apple has made some changes to USB security:

To improve security, for a locked iOS device to communicate with USB accessories you must either connect an accessory via Lightning connector to the device while unlocked or enter your device passcode while connected, at least once a week.
If you use iAP USB accessories over the Lightning connector (including assistive devices and wired CarPlay) or connect to a Mac/PC, you may therefore need to periodically enter your passcode if you have a passcode set on your iPhone, iPad or iPod touch.
Be sure to check out our hands-on videos coveringAirPlay 2, as well all of the other changes we have discovered thus far in thefirst beta of iOS 11.3.
