Manchester SC have confirmed I need a replacement AP computer but there are supply chain constraints.... Awesome
I've just managed to get mine working again this morning. Similar to what I tried before but with the car unplugged.
I unplugged the car, closed the app on my phone and made sure I didn't wake it for a day.
Opened the app this morning (probably 28 hours or so since I closed it) went to
security > sentry mode and enabled it. Then tried viewing the live sentry feed and all my cameras seem to be working again.
Jumped in the car and tested cameras, AP, TACC etc and all seem to be working. I suppose all those things including auto wipers etc are all dependent on the cameras being operational.
So all back to normal but there's obviously some horrendous bug in the software/hardware that is cleared by the car falling into deep sleep when disconnected from charging and left to sleep for over a day.
I am guessing it will rear it's ugly head again in the not too distant future.
