2019.8.5 is really annoying.
Mine AP2.0 is rebooting almost everyday.
Today, after I summoned the car into the garage, plugged the charger in like everyday routine - then walked away. 2 hours later, When I was driving another car into the garage, I heard the music. Looked into the X passenger door - omg the car was awake & unlocked. All door closed, no keyfob inside, no passive entry. Opened the door then closed made no any effect. Had to reboot the computer to make it normal again.
I had this exact same issue happen to my car. I had to manually power it off. Ever since that happened, I check my car via the app to see if it is awake. The way to check is to see if Media option shows in the app after you have walked away. This means the car is awake and you need to manually turn it off or reset the computer to avoid battery drain.
