Glad to help, but I am sorry that I will probably disappoint you with my answer: in my opinion, this is not a bug, it is desired functionality (Tesla's desires, of course) and the software updates are just catching up to the tumultuous changes coming from the top.
The way Tesla restructured the Autopilot software features, when they made price changes in March, makes it such that you only get TACC and Autosteer features with the first Autopilot (AP) "level". You have to pay for the "Full Self Driving" (FSD) level to receive Summon, Autopark, and Navigate on Autopilot.
Although I completely disagree with this change as a customer, I do understand why Tesla is doing it. They have a fixed cost with installing the full hardware suite in every Model 3, but only make margins when they sell software to use that hardware.
Before the price changes, I would be willing to bet very few people bought Full Self Driving for the extra $3000, since it did not add any actual functionality. Enhanced Autopilot (EAP) at $5000 provided everything that is available today, but FSD provided nothing more but future promises.
With the price changes, because they moved some existing functionality to FSD, they can entice people to pay $8000 (AP+FSD) instead of $5000 (EAP only) in order to use those extra features now.
I know it's a bit unfortunate for those who ordered after Feb 28, but it is this way now. Until it changes again next week..
