Cybertruck Suspension

You'll soon be able to adjust the Cybertruck's suspension height from within the Tesla app. This was first hinted at last month, and now thanks to Tesla_App_iOS, a new Cybertruck suspension image has been found within the app.
It shouldn't be long now before this feature becomes available to Cybertruck owners.
Service Improvements

Tesla has made additional improvements to the Service area of the app. In particular, the scheduling UI has been improved, making it easier to jump around and pick a date and time slot that works for you.
On the Service history screen, you can now also pull down to refresh.
AI Assistant

Tesla has improved their AI assistant in the Tesla app. The assistant is located under Service when you tap on 'Ask a Question.' Although this assistant has been powered by AI for a little while now, it has now been improved with better response "bubbles."
It now also features personalized information from your vehicle for the first time. For example, you can ask it what are your vehicle service alerts, and the assistant will come up with a list of alerts.
Tesla's AI assistant was also recently added to Tesla's website.
