The culprit turned out to be that the Tesla people forgot to turn on the switch of the circuit breaker labeled. Once that was turned on, the App issue went away. The Tesla customer service through the phone was cmpletely misleading me.
I have exactly the same issue and called Tesla. They told me that there is typo in the system that caused my problem. That is very surprising as there is no any verification step to prevent this for such a well-established company. I am still waiting for their solution.
