To all experiencing the problem of not being able to pair ipad 10th gen to 1st gen apple pencil (2nd gen pencil WILL NOT work with with 10th gen ipads.)
PLEASE READ MichelPM's posts. This fix is 100% accurate and confirmed. Apple stores know this is a problem but Apple phone support is giving the runaround of update and charge both devices to fix which WILL NOT work. Further talking to apple support, they finally admitted that the engineers know about the problem.
Contact apple support and tell them you need the USB-C to lighting adapter (part number MQLU3AM/A) and that it did not come with the pencil you bought. Insist that they send you one no charge - it worked for me. (link below - also in MichelPM's post) .
USB-C to Apple Pencil Adapter - Apple You can pay the $9 + shipping if you want or insist they send it to you free. Either way - you NEED it to make the pairing work.
As MichelPM said: "Without this adapter, you will never be able to pair/connect and charge your Apple Pencil.
The sooner you order this adapter, the sooner you can start charging, pairing/connecting and using your 1st gen Apple Pencil."
Thank you for your help MichelPM !!!!!
