I'm using a Moto X (Gen 1) phone. If my search result alllows an audio answer ("Who is Charles Lindberg?") I get the answer via audio. But if it's a more indepth question, I get no Google results, just a blank screen below the Google logo and my search question. My questions are showing up on the search bar. Things have lways worked super in the past, I'm afraid I may have changed a permission or other configuration inadvertently. Ideas?
