I spoke with Tesla again to find out why I’m only on 5.15. They checked the log files and determined that 5.15 was pushed out to me several weeks ago and it failed. Once it failed no further updates were attempted. Now that the system has logged a successful update I should hopefully get back to a normal update cycle. I’m not sure how long I would have gone had I not contacted them to request a push. But for those who say just be patient, I’m not convinced that is good advice. If you are four versions behind everyone else there is probably a problem with the connection that the folks on chat can easily fix, so why wait around if you don’t need to.
