We develop an app for email, calendar and contacts.

Inspired by the showcase Calendar App at https://developers.google.com/cars/design/automotive-os/apps/calendar/interaction-model/overview we added Android Auto support to our application.

It works and was approved by the PlayStore.

Without any changes to the Android Auto part our current update was rejected with "Your app does not fall under the accepted app categories."

Our appeal failed without any explaination, just repeating the text above (and highlighting .

The app name is ISEC7 MAIL (com.isec7.android.med)
