Apple Pencil Pro connecting but not working

I've been having issues for months with my Apple Pencil Pro. It intermittently stops working with my Ipad Pro. The pencil connects perfectly, it charges, it has a new nib. But doesn't register on the screen, and nor does the "squeeze" function register. Generally, with patience and lots of reconnecting (which I'm not sure actually does anything but pass the time tbh) it starts working...usually like a biro thats running out of ink to begin with...before it's then "back".

However, this time I cannot get it back. It's been a week.

Ipad is updated. Apple pencil is charged and still connects via bluetooth normally. The nib has been changed multiple times. There is no screen protector.

What do I do?
