I'm glad I'm not the only one. I've intentionally stayed on 7.1. After that I read about more frequent AP nags so I intended to wait for a later update where that got adjusted. Then they changed AP to primarily using the radar over the camera and I read about people experiencing phantom breaking, so I waited to see if that got resolved. Then they made the top bar controls disappear, then took colors out of the maps and made them lower cotrast and harder to read, and I didn't want any of that. Then v9 and I sure as hell didn't want that! It has been a series of usability downgrades from my point of view and I have managed to avoid them. Apparently my 7.1 can't force an update. I get the notifications and clock icon but I dismiss them and no update runs.
My lease on this 2016 AP1 Model S is up and I have an I-Pace on order. Other than driver asistance that doesn't measure up to AP it has a lot that I like: nicer interior, CarPlay, front and rear cross-traffic warnings, 360 degree camera views, heads up display, and gesture liftgate. Also the suspension adjustment is by physical buttons that are always accesible. No navigating through screens to find the suspension controls and not getting there by the time I'm at the bump or dip.
"But supercharges!!!" I don't need a supercharger network because I fly instead of taking road trips, and with free unlimited supercharging not included (except when the want to unload inventory) Tesla loses its advantage anyway. If I'm going to have to pay there are DC fast chargers located more conveniently to my routes than where the Superchargers are.
They have over the air updates but you have to enable that and affirmatively get and run them if you want. They fix bugs and make small improvements but they don't do huge UI overhauls like v9. I'm good with that.
