Using MBA, iPhone, both with latest updates. Getting same issue described in other comments. Tried disabling VPN, virus protection, airplay and sidecar. Logged into same wifi network, bluetooth on, not screen sharing to any devices, AirPods not connected. Even noticed I was in do not disturb mode and switched to focus mode. The only think I didn't try is doing all these steps during day time. How to get this 'feature' to work? Or did Apple give the ultimate "MacRumor" by showing this feature works when it doesn't?
