Steeler

Update:  I got it working!!  Here's what I did:

• I reinstalled Android Auto on the S8 (probably didn't need to do this, but I figured why not)
• Used an Anker Powerline+ USB-C to USB 3.0 cable (3ft) directly connected to USB-2 on the receiver (yes, I know, that cable its not certified by Pioneer but the certified cables didn't work)
• Reset the input settings on the Pioneer.  Went from USB2 to HDMI and then back to USB2....and that did the trick!!  Not sure why or how or whatever, but it's working.  I tried the certified cables that I purchased last week just for giggles and they're still no good.  The Pioneer and the phone like the Anker cable for whatever reason.  Maybe because it's USB3?  I don't know 

Thanks tekki.  Still no good though.  I tried two of the certified cables using the Pioneer extension cable and the directly connected to the receiver; same results. Very frustrating.  

I'm going to reach out to Pioneer support to see how far that takes me.  

I'm having the same issue with my 8100 and the S8.  No response on the phone or 8100.  It charges, but that's it.
