Surface pro pen issue

Hi, I’m still having issues with my Surface Pro 12 tablet, the pen is unusable, clicking all over the place. An iPad with Apple Pencil works fine, but on the Surface Pro I can only use my finger for takeoffs, which isn’t ideal. I’ve tried adjusting the pen settings but no luck. Any help would be appreciated, thanks.​​​​​​​​​​​​​​​​
