Update for my failed keyboard. My main gripe is, don't let Apple support suggestions totally influence you. I took my pro pad and keyboard to an Apple Store. Had to make an appointment, drive 80 miles and use up a day off for this. They ran a quick diagnostic, couldn't find an issue. They cleared memory and did a restart from iTunes, the same thing I did at home. They said if it happens again exchange the keyboard. Three hours of run time at home the keyboard freezes and also freezes the iPad. Any work you're doing is lost, you have to power down for things to work. Exchanged keyboard and it's worse. Minutes between keyboard fail. I get hold of Apple support. They think maybe the iPad is defective, what I thought in the first place. They asked if I wanted to set up a return. Yeah,better than driving to the Apple Store again. This time they said I could take it to a local authorized Apple warranty service dealer. In town, six miles away. Why didn't support suggest that in the first place? They couldn't answer that. I bought my iPad online and couldn't even buy a keyboard for a few weeks later. So returning the iPad was out. I dropped off my iPad and keyboard to warranty center. They said it may be a few days to test it and they'd call. They emailed the next day. The iPad is defective, a new one would be there the next day. Now I'm totally happy with my iPad Pro and Smart Keyboard. But for a few weeks I was very disgusted with Apple in general.
