I am currently on IOS 18.1.1 and I am having the same issue with Bluetooth. I have reset network settings and I even went as far as completely wiping the phone and setting it up as new without using a back up and I'm still having Bluetooth issues, screen responsiveness issues and push notifications delay or not working at all.
Here is my question, I was an early adopter and received my phone the day it came out. Who else is early adopters and are having this or any of these issues?
I ask because I know a few people who got their 16 Pro's this past week and they are having no issues whatsoever with anything.
Which makes me wonder if it's not just software related but also could be hardware related (antennas/radios/screens) that is causing bluetooth issues, notification issues and the screen not responding to touch.
