As I understand it— someone at Android needs to authorize the app to work with AAOS (Android Automotive OS) which is what we fun. It is akin to having apps that not all phones can download. There may be some way to side load the app but I haven’t actually seen or read about that anywhere on these forums, nor on the Polestar forums.
In other words, until Android or Volvo approve the app for our cars, we wont be able to download it normally/natively. I wouldn’t hold your breathe for that app to come anytime soon. Volvo owners are still waiting for apps that Polestar has already gotten, like ABRP.
