Which version did you update to? For non-FSD-beta, the extra camera is available starting 2022.44.25.1. If you are using FSD Beta, the holiday features are rolled out in a different version (I believe it's 2022.44.25.5).I got the update too on my MYP. Still playing with the new features. But I cannot get the interior camera to work. All the other cameras on sentry mode work just fine. I do not see the extra dot for the interior camera. Do I need to click or activate something else?
