Apple pencil not recognized
iPad Pro 9.7 inch and Apple Pencil.
Apple Pencil paired and working fine. After a variable period of time, iPad no longer recognizes the Pencil. Pencil is fully charged, but even when plugging it into the Lightning port the iPad fails to recognize it (although it remains listed under Bluetooth devices as not connected). Restarting the iPad causes the Pencil to be paired with the iPad.
I've been to the Apple store where the problem was duplicated and it was suggested that we reset the iPad to baseline. After a long restore (at home), it worked for a short while, but now the problem has recurred.
I've checked and the tip is tightly screwed on. I've charged the Pencil via a direct USB connection and battery is listed as 100% after I've restarted the iPad.
Any suggestions?
