2018 iPad Pro sync over Wi-Fi
On the iPad, I go to Settings, General, iTunes Wi-Fi Sync and I get a screen with the usb cable coming up from the bottom with an arrow pointing to the iTunes logo. Across the top is says "To enable Wi-Fi syncing with iTunes, connect to iTunes on your computer using a cable and click "Sync with this iPad over Wi-Fi". ...
Which I've done. and I've undone it and redone it. I've done a hard reset on the iPad, I stopped and restarted iTunes. When I "undo" it, I sync and make a backup (via the cable). Likewise, when I "redo" it I sync and make a backup. The backup times change.
Curiously, it will sync over Wi-Fi if I go to iTunes and hit Sync and iTunes sees my iPad via Wi-Fi. But, I can't get the normal "Sync Now" display on the iPad. The sync via Wi-Fi works fine for my other iPad and my iPhone.
