Maybe it is a recent thing, It seems that if you reset your score too many times, Telsa penalizes you. I reset my score 4 times in total (by opt-out, driving a bit, waiting till the score disappears, and requesting the beta again). For the first two times, I was able to get the score back in a few hours. After the third time, it took me a couple of days. After the 4th time, it took 5 days for the old score to disappear. It's been 7 days, the safety score still hasn't shown up on my Tesla app. From the post above, maybe this has nothing to do with the reset?
