I know it's bad form to resurrect on old thread, but it' sure seems relevant to my current issue.

My AA has been working intermittently with my new phone (Xiaomi Mi A2). It always worked fine with my Nexus 6. Also, new apps (Slacker, etc) were not showing up in Sync Apps.

I went into my AA settings on the truck. I had three options, I believe it was "Enable/Disable/Delete". I chose delete , thinking that I'd delete the phone pairing and would just have to re-pair it...Nope.

AA seems to be gone from my truck entirely. It still starts up automatically on my phone, but there is NO mention of AA anywhere in my truck's stereo menus.

What's next? I'm assuming that I'll need to try a manual Sync update or maybe a master reset.

 

OK... Short answer, fixed.

Master reset did it for me. It wasn't as bad as I thought it might be. All radio presets stayed put. No big deal really.
