The first thing that I noticed on my 2021 Model Y when it was delivered on October 30th was the sluggish nature of the screen in comparison to the 2020 Model 3 that I traded for it. Loading speed for the browser was especially slower. I chalked it up to a difference between vehicles and have lived with it. Rebooting, using the steering wheel buttons - with or without the brake - is also much slower. Since the 18.2 update, my browser will open, but will not load a page. This is the same for wifi and the Tesla mobile network. The page I use most often down here in the Panhandle of FL is weather.com . I find the radar view useful as each new front rolls through from the west. I've scheduled a SC appointment to check it out. Anybody else with this problem?
