It's flaky still. It may work or may not. The only thing that seems to work is the Tesla app; other API users like Remote S and TeslaFi are getting intermittent results or don't work.
Do NOT call Tesla Support, they can't do anything and they know all about it. This has the smell of a temporary fix that was put in for the night, and a better/permanent one to be rolled out today. All a phone call does is tie up people that could be helping send Roadside to owners stranded. I would have hated to be someone with a flat tire anywhere Saturday!
The Tesla app should work if you keep trying.
