Hello. After updating my Macbook pro (14, M1Pro) and my 2022 iPad Air 5, universal control stopped working. Nothing helps, I turned off and on handoff, wi-fi, bluetooth, restarted both devices several times.
On my Macs preferences (monitors), there is only an option (when I hit “+”) to extend screen on iPad. No option for universal control.
Also I realised, that the sidecar option is only when my iPad is connected via USB to Mac. Wirelessly works nothing. Both devices are connected to same wi-fi.
Upon investigation, it was found that a Handoff bug might be the cause of broken Universal Control in the latest iPadOS 16.4 and macOS 13.3. @Iraqdad complained:
iOS 16.4 and Ventura 13.3 has killed my universal control for my iMac 27” and my iPad Pro which were both working seamlessly before up dating. Also my iMac now cannot unlock with Apple Watch 6. The iMac cannot connect (sync) with my watch. Thank you Apple. How can we fix this?
