Here is a tip I could not find it anywhere on the interwebs. My Apple Pencil (which I use extensively to highlight PDFs while reading in Endnote and other apps) stopped working. The iPad could see it, knew it was there, fully charged, but when I went to write, highlight, or draw, nothing. No solutions were found on the internet and forums, so I made an Apple Store appointment. First thing the person helping me said, “double check that the tip is screwed in.” Oops.
So, screw it! If your Apple Pencil is not drawing but is seen by the iPad, first double check the tip is screwed in tightly!
Your welcome.
