If previously it was enough just to click on an empty space on the map, now you need to swipe up on the search bar. But to make the interface appear again, you still need to click on the map.
Clicking on an empty spot (when the interface is not hidden) now just shows the coordinates of the specified location on the map.
Recently, Android Auto faced a GPS signal loss issue in Google Maps. The main issue is that it isn’t occurring when using the Google Maps app outside of Android Auto. Users report that the problem only occurs once the phone has been put to sleep, with the screen turned off. Currently, the solution is still unknown.
