Hello,
Have Android Auto installed via GrapheneOS Apps repository on version 12.0.642034-release and no updates available, but Google Play Store is showing version 12.2.642414-release being available.

Is this correct as thought Apps repository should mirror Google Play Store?

    Version 12.2.642414-release is in the Alpha channel currently. It should arrive in Stable in a day or 2. If you want to update now, go to Apps > Android Auto > Three dots in top right > Release Channel > Alpha

      Just change the Release Channel for an app, and you can see the "Available version" underneath the Install button.

      The new version of Android Auto doesn't seem to have reached Beta yet. Is the version for Alpha a display error or is something holding the update I wonder?
