On a whim I loaded 11.1 public beta 2 on Monday evening and my BT has worked rock solid on that version from Monday night to last night.
Then last night I wiped my phone and installed the latest 11.0.3 update that came out yesterday to see if they fixed anything and BT went back to not working. There is DEFINITELY an issue with 11, 11.0.1, 11.0.2 and 11.0.3. I don't think it's the 8+, I think it's the current builds of iOS11 outside of the beta versions since beta 2 works perfect in respects to BT and everything else doesn't.
From Apple's previous responses to me, I'm surprised that haven't suggested yet I replace my Nissan with a vehicle more compatible with their software, LOL.
Nice, I’m going to load b2 tonight.
