Pretty (very) sure that this is all part of the 30-day trial. I took delivery on 3/12 and bought AP, but not FSD. I have all the AP & FSD features as part of a 30 day trial. Once my 30-days are up, I fully expect I'll lose the FSD features (Nav on AP, Summon, etc).
Additionally, if you go to your account on Tesla.com, you will see a section for Autopilot Upgrades. Since you bought AP, but not FSD (like me), you should see that the only option is to purchase FSD for $5500. This is the purchase price after delivery, but before the 30 day trial is up. After the trial, you will most certainly lose FSD and the price will go up to $7000.
FYI...I believe I saw the trial information on the touchscreen after my car installed 2019.5.15.
