I can relate, I understand the Covid19 difficulties and all that, but other than connect my phone and handle the paperwork my assigned service person pretty much left me on my own... "You can get in the car and check things out while I handle the paperwork" he told me.
I never had stepped in a Tesla before so it took me a while to find out how things were working on my own.
2 days later I found out where the "owner manual" was and went by a lake to read it all and try the different funtionnalities away from people and risk accidents
