I can no longer wake my Model 3 using the phone app when it is asleep. If the car is idling (like when sentry is active) I can access it remotely with the phone app. But if is fully asleep the app cannot access it. My car is parked in a good signal area with LTE and WiFi available. Although once asleep the WiFi connection drops which is to be expected. Has anyone else had this and no how to fix it? When waking from the phone app I think the Tesla servers sends a command via the phone network to wake the car. Overseas people have reported their cars not waking was related to Tesla changing mobile carriers in their region. But they still use Telstra here so it is probably not that. Any ideas.
