Look to the tip

I charged my Apple Pencil, paired it (once again) with my iPad, and was all set to draw something for some kiddos.

Nothing.

I turned Bluetooth off. I turned Bluetooth on. I asked the iPad to forget the pencil. I re-paired the devices. Nothing. I restarted the iPad. Nothing. I turned Bluetooth off. And so on.

I finally discovered that the problem had nothing to do with pairing devices: the pencil’s tip needed tightening.

I found the solution not at Apple Support but at iMore, where tightening the tip is the first suggested fix for a non-working Apple Pencil.
