I received this update and it did not fix the "Cruise Control Unavailable" bug. Tesla knows about it, and attempted to push an update yesterday to fix it, but that didn't work either. I really hope that I get to use Autopilot soon.....I've never had that bug on 2019.16.3.2, but I got it twice today - on the parking lot and in the garage. Just as I pulled into the parking spot, it flashed a warning that front camera has obstructed view and cruise control is unavailable.
I also noticed that the car refuses to go into sleep now. It used to go to sleep after ~15-30 minutes of inactivity when parked in the garage or on the driveway as Sentry mode is deactivated at home. It did sleep at night when plugged in, but after I drove it this morning, it sat all day awake.
