The phone I tried the Android Auto with is Samsung Galaxy Z Flip 3. I can try it out and look for settings in few hours. I also remember Mi Mix 3 not really working in my car (but I didn‘t have enough time to check the settings and find out why).
Hey! Not really, I didn't get any more issues since then. What I did was pretty much a clean slate start. Reset the MA1 dongle, reset Mazda Infotainment, unpair both Mazda infotainment and Dongle from my phone. Then started over again. Connect dongle to USB, Pair dongle to phone with bluetooth, and I think that's all that was needed.
