I have been running GOS for around 6-8 months. I have the required Google Sandboxed Play Services installed as per the instructions. My OS has been updating properly as far as I can tell.
I recently got a new car head unit and want to make use of Android Auto but it will not install. Some of the early attempts were certainly user error as I found recently that I need to install the app through the GrapheneOS App store. Looking into this today I see that there is a newer version of App store (version 24) that changes the name from Settings | "Apps" to Settings | "App Store." My phone still shows "Apps" so I tried to figure out how to manually install the latest version (so I could then attempt to install Android Auto) but was unsuccessful.
So I really have two questions. How do I update the App Store if it is not happening during the usual update procedure? And am I missing something about how to successfully install Android Auto?
I know this is a bit of a ramble. I'm a newbie on the forum and will try to get better with my questions.
