Same happened to me when i picked up last week. That and my GPS stopped working and the map screen was glitching like crazy. They sent me a firmware update that took care of all of it. Had driven over 100 miles on pickup day and it wasn’t calibrating, after the update it only took a few miles and AP became available.
I did see all the AP items in the AP menu right from the start though so you might have another issue there. Check your purchase agreement, it should have AP itemized on there with no price. If that is there just ask for the firmware update to fix your issue. If it is not on your purchase order then you have a car without AP included (highly unlikely)
