Welcome to HP Support Forums. 🙂
I came across your post and would like to assist.
I understand that the HP pen that came with your HP Spectre x360 Convertible 13-ae0xx has no pressure sensitivity.
During my research, I found that if the option you're looking for pressure curve adjustment, then is not available on HP Pen.
Secondly, you may review this HP document as it provides a number of steps that help in resolving pen related issues: https://hp.care/2yvFxZB
I genuinely hope the issue gets resolved without hassles and the unit works great. Let me know how it goes.
Cheers! 🙂
