There can apparently be several possible causes of this issue. I have iPad Pro 12.5in 2018 edition and Apple Pencil 2nd gen. For me, the triggering factor was simply having the pencil drain to 0% battery (not for long - only like 5 minutes at 0%). Suddenly, although attaching the pencil to the magnet caused the “Apple Pencil” message to show on the screen, no battery percentage indicator would show, and it would not pair again after I “forgot device” from iPad Bluetooth settings . I was able to fix it finally, and some of these steps may not be necessary, but this is what I did: The only way I got it to recognize it again was to
1) forget Apple Pencil device under iPadOS settings—>Bluetooth , then turned Bluetooth off and on again. Don’t think it matters if pencil is attached or not, but feel free to try it either way.
2) set pencil on magnetic surface of ipad
3) turn off iPad by holding top button and volume up side button then sliding the screen button slider to power off.
4) turn iPad back on by holding top iPad button
5) after putting in my passcode, the iPad recognized the pencil attached and the indicator finally said “40% Apple Pencil” and it worked again.
I was close to buying a new one due to all the reports of lithium ion battery irreplaceability and other instructions not working for me. Glad i didn’t.
