apple pencil 2nd gen cannot work on ipad air 4

Hello,

I want to ask something, why my apple pencil second gen cannot be used @ cannot be paired with my ipad air 4 gen after updating ipados 16. (currently my ipad air 4 already in ipados 16.4 and still the apple pencil is not working).

I hope you can help me with this problem,since i use it a lot.

Thanks for your cooperation

Sincerely
