Swegman, none of old sites work in Fl. confirmed by Tesla . Good luck.
All brand new ones work here on 210, and one in east jax, number 4.
Tesla charged my car at the Rivera Beach FL superchargers next to the service center (original location, not the new superchargers that recently opened nearby) without issue on January 14. Those superchargers have been there for a couple of years. Car charged without issue.
I charged at St. Augustine FL on January 12 without issue and those superchargers have been there for years.
Also, I do NOT think the issue is related to v9 being installed on our “old” cars because I have NOT installed v9 on my car. I am still running v8.1 (2018.34) on my car. As I indicated above, Tesla service said the issue was with respect to a recent firmware upload to the superchargers and that the bug was being addressed with an update of the supercharger firmware.
