Apple pencil not working
I use iPad pro, purchased apple pencil one year ago. It is connected through bluetooth, but recently, it does not work. I can see that it is fully charged. The tip is recently renewed. I rebooted the iPad and also reconnected the bluetooth but still not working. I purchased one more Apple Pencil but still it is not working. What can I do here?
iPad Pro 10.5-inch, Wi-Fi, Cellular, iOS 11.4.1
