Been using it for over a year.
My banking app just stopped but idk the reason yet. Calling today to figure it out.
It depends on your tolerance and how much permissions you give apps.
Here is how I run it. And I welcome people to point out any potential security or privacy holes:
Pixel 7a
Aurora store
No permissions allowed on Google play store or Google play services.
No Google apps that require any sign in
I do have Google and assistant installed and sometimes I play with permissions to get voice control to work on Android auto but mostly I remove all permissions.
Minor annoyances:
android auto voice control is wonky
With play services denied network access certain notifications won't work (life360 for example) - but generally I don't care because I hate notifications.
