As of this moment, August 26, 2021, the new Tesla app (iOS at the moment) has been refreshed. The new update incorporates a refreshed user interface and several new features.
Some of the new features include direct access to the Tesla online store, where users can purchase accessories and apparel items, the ability to manage multiple vehicles with a more intuitive interface, a more accurate depiction of the vehicle's depiction (like now showing the correct color of the car's interior), app's user profile and more.
Like always, it is a free download from the app store (the Android app should get updated soon, if not by the time you read this). If you haven't received the update yet, go to the app store and download version 4.0.0 today.
