Upgraded from 26.3 to 28.3 in this morning. Got the notification on my iPhone at 2am last night. Manually did the UI restarting and the car power off/restarting after the upgrade to avoid any problem from previous version. Drove 50 miles already, and so far so good.
Same here, maybe why I got an update after about a week I got another update. I had been noticing each time I got in the car it was less than I thought i would be. So then charged late Thursday to 80% (279 miles for me) and didn't drive at at all yesterday. This morning it was 268.
