iPad Pro Keyboard "This accessory is not supported by this device"
128GB, 12.9" iPad Pro running iOS 10.1 (problem occurred with previous iOS too).
Smart Keyboard all of a sudden doesn't work. Error message "This accessory is not supported by this device".
Have cleaned contacts, rebooted, hard rebooted, and upgraded to the OS to iOS 10.1. No change.
It has randomly worked a few times, but seems random. One day couldn't type a web address in Safari, next day I could. Hasn't work a few days in a row now.
Thoughts?
iPad Pro, iOS 10
