Took almost 2 months to get my registration documents in, after Tesla screwed up multiple times. I called them after a month only to find out they had not submitted anything because they claim I never uploaded proof of insurance. Mind you, I use Tesla insurance, and I am required to provide proof at least 2 days before pickup in Texas. It took another couple days to get that sorted out, but I had to call multiple times and spend hours on the phone.
In the end, Tesla had to pay penalties to the county for not registering within 30 day as well as not paying the new car taxes that they collected from me at point of sale.
I'd recommend you call them to find out what's the holdup. They will email you a second temp tag.
