As to 2.0.28:
Two things. First, Lucid states that you should not have vehicle plugged in when you install 2.0.28. I didn't see that and I installed it with the garage charger plugged in and charging. However, everything went fine.
Second, and I don't know if this has to do with 2.0.28 or an earlier update, but I just noticed that you can now control the rear window shades from the front driver seat. When I first got the car you couldn't do that. I even discussed it with the Lucid representative. So somewhere along the way that was fixed. Maybe 2.0.28, I don't know. This is why Lucid should give specifics in their updates.
