Did more testing today. I can currently deploy to either cabled device from PC and Mac when wifi sync is disabled. It might be necessary to reset the device radio after disabling wifi sync (toggle airplane mode or reboot).
Network deploy isn’t working for me. iPad plugged into PC, deploy from Mac to All_iOS_On_XXX results in message ‘timed out while trying to connect to a mobile device.’ Plug iPad into Mac, deploy from PC to the iPad detected / shown in the launch menu results in the same message. In both cases the network devices are visible to the network without sharing the devices first. But the launch fails if the device is or isn’t shared.
