I haven't seen most of the issues you describe, but I do know that AA is incredibly finicky with the quality of cable you use. When I first bought my car I would use a random cable from Amazon and Mazda's infotainment would straight up crash (can't blame that part on AA though). Mazda's infotainment is pretty notorious for being terrible; that it takes so long to connect (and get past the safety disclaimers EVERY SINGLE TIME) is truly annoying. I will say that I just bought a wireless AA dongle off Amazon and since I got that it's a lot more reliable because I'm not swapping cables all the time, though my Mazda still will take a while to connect to AA, then start playing my phone music, then switch back to radio for now apparent reason. It feels like the two subsystems are competing.
