Since downloading iOS 12 public beta 1, I have had random crashes and the springboard information back to home screen. Tends to happen late in the evening (usually when I am walking my dog) but also sometimes just randomly through the day especially when I wake the screen by tapping it. Also I just realised it doesn't send music to my HomePod although it can start and stop music it activated from the home app. Am I alone or is this a common bug.
