Just updated from 42.2 to 42.3. No changes in release notes (Nav on Autopilot still missing for me in the release notes and as an option to enable in the autopilot menu). Service center indicates maps were not up-to-date this afternoon, but suggested they were nearly finished updating just prior to my car downloading & subsequently installing 42.3 this evening. Hopefully the maps will update/finish updating overnight (??) and NoA will be available tomorrow.
