I've had a couple of recent updates and am on 2020.32.5 in the UK. If the car is locked I'm no longer able to communicate with the car using the mobile app (Android) until the car is unlocked. The mobile app shows the banner "Waking up" and eventually times out without successfully connecting. Both my wife's and my phone have been happily connecting until recently but both suffer the same issue with the app. I don't think it is an issue with the phone, although it's possible that it could be the app, if not the car.
Once the car is unlocked, either by myself or my wife the app successfully connects to the car.
Has anyone else come across this? Is this something that of Tesla is aware of?
