While browsing, tapping into any artist shows nothing, no options while using the music app on CarPlay. For context, I have a lot of music (7,000 songs and 430 artists), and my own local files transferred from iTunes (Purchased MP3s and M4As from different sources).
Also, the volume normalization (I believe it is now included in what is called "Sound Check" in the iOS 18 Music settings) stopped working. There is no normalization going on, which makes me have to manually change the volume when playing on shuffle.
Hope you can fix this for the upcoming update!
