I have only signed up here to say MASSIVE thanks to the person who came up with the hairdryer idea. I was devastated when I tried to pair a NEW Apple Pencil 1st gen that's been most likely sitting in a drawer somewhere for god knows how long. It was kept disconnecting, not pairing, nada nada. Heated up for 1 minute and voila, like the above issues never happened. Connected and started charging straight away, blown my mind. Madness. Huge Kudos to you man.
