When browsing e.g. the album list in Android Auto, it takes three taps to go to a specific character - once to open the first-character selector, once to select a character, and then instead of going to all albums under that character, it displays a list of… just that one character. Which you have to tap to get to the list. Removing that last step would be more intuitive.
Instantly go to the list of “Albums/Artists starting with X” instead of first having to tap X again.
@LVA , just so you know that you are not alone out there: I have the same issues with AA and discussed them a couple of times with @Tolriq already, but they are based on limits on the Google side and not much can be done it seems. Even when you manage to get voice commands routed to Symfonium, the results are not always convincing because Google Assistant seems to think that people only want to play songs, not albums…
