Recently my smart keyboard has had problems connecting. I had to disconnect and connect many times, and then it would work. I also got "this accessory is not approved to work with this iPad" (or something similar) message. I tried to clean the connectors. Since today it doesn't connect at all. I will visit the Genius Bar tomorrow. I guess it should still be under warranty (bought in March/April last year). But has others had this problem? I general I'm worried about the durability of the keyboard. I wanted to buy AppleCare+, but the smart keyboard is not covered. As I expected that to be the weakest part, I didn't buy. Unfortunately, as expected, that was the part breaking first.
