CarPlay Volume adjustment not working
Like a few others, I seem to have an issue with my iPhone 13 Pro Max; when it is connected to CarPlay it often won't allow the volume to be adjusted, using either the volume knob or the steering wheel controls. This issue seems to be linked to the particular phone since iOS 16, as other iPhones are fine (I have tried iPhone SE and 12 both were fine).
