Apple Pencil 2 suddenly stopped connecting to iPad Air 4

I have an **iPad Air 4 and Apple Pencil 2**, and my Pencil has suddenly stopped connecting. I’m not sure when the issue started. When I attach the Pencil magnetically to the iPad, the Pencil animation appears on the side of the screen for a few seconds, so the iPad seems to detect it. But then it disappears and nothing happens. It doesn’t show up in Bluetooth No battery level is shown No “Pair” button appears I’ve tried restarting the iPad I’ve tried forgetting the Pencil and reconnecting it The iPad is fully charged I’ve also updated iPadOS recently while trying to troubleshoot this, but the issue existed before the update, so I don’t know if it’s related to iPadOS. Has anyone experienced this with an **iPad Air 4 + Apple Pencil 2**? I’m trying to figure out whether this is likely a Pencil battery/hardware issue or something with the iPad.
