I don’t think you need a Google account to use Sandboxed Play Services in general. Maybe some specific things that require you to be logged into the Play Store but overall I can use Android Auto and other things I need without being logged in.

What did you find you needed to be logged in for?

I’ve been using GrapheneOS on my phones since the Pixel 3 and I have not had this issue when using Verizon. For the other person maybe it was a different carrier? Or some issue a while ago with that carrier and GrapheneOS.

And Nintendo Switch wasn’t availabley yet last I checked.

Yeah I saw the takahē in Zealandia and one other zoo. Would have been cool to see in the wild if possible in the preservation areas the have.

Probably a Takahē in New Zealand but in captivity.

But out of curiosity what apps didn’t work for you that were deal breakers?

Works for me on Verizon and has for 5+ years. Google Fi even works as I’ve tried that with a different phone on GrapheneOS.
