I'm in the same boat. Took delivery on 4/18/19. Opened a service request (which is tomorrow at 8am). They contacted me a day after opening it, and pushed 2019.7.105. I asked them why unconfirmed lane change and sentry mode was still missing, and they went silent. Won't respond to text messages or left voice mails. My Navigate on AP also has annoyances that are fixed in 2019.8 (hard braking in lane changes, aborted lane changes, drift to left on lane merge, etc).
Don't get me wrong - I LOVE the car. Just would like to get up to date. Before reading this thread, I had suspected it was because of HW3.
Since I live near the Tesla factory, my appointment is at the service center that's just south of the factory. Hopefully I'll get some real answers tomorrow morning.
