I'm seeing a message "Update Android Auto - This update will soon be required to use Android Auto." Anyone else notice that?
Android Auto Compatibility
I posted about this just last week: https://discuss.grapheneos.org/d/15928-android-auto-required-update-notification
There is a new version in the GOS app store in alpha release, so it must be in testing.
But to answer your question, yes I did have the same message prior to updating to the alpha release
