OK, I've been using AA quite a bit lately and here are a couple of observations.
1- My phone (Pixel 8) gets pretty warm when using AA. And that means crazy drain to the point of anything long distance means I'm going to have to plug it in.
2- AA usually launches automagically when I select it, or if it was being used the last time the car was driven. But occasionally, the phone doesn't seem to want to connect via BT unless I explicitly go to the car's"connected devices" screen and select it.
Observation one is clearly not a Lucid implementation issue. And observation 2 probably isn't either.
Over all, I give the AA implementation an A. It was a long wait,but all is now forgiven.
