iPhone 8 bluetooth issues

My new iPhone 8 is having all kinds of wonkiness with bluetooth. It refused to pair with my AirPods, repeatedly dropped connection to my 2016 car, routinely loses connection with my series 1 watch and refused to connect to unlock my laptop (all things that I had no issues with before moving over from my iPhone 6). Apple support told me to erase all content, reset and go through a reinstall from a backup (and all the password re-entry etc.) which I did wasting a couple hours of my day. Their remote diagnostic said bluetooth was fine and some of my apps (none to be named) had problems necessitating this restoration from backup. Needless to say, the issue does not seem solved. Anyone else having bluetooth issues with the iPhone 8? All of these bluetooth connectivity issues worked flawlessly on the 6 (with iOS11 and all prior iterations I had) so I may just sent the 8 back and live w/ my 3 year old battery for a while longer.....
