I have an lg stylo 4 and it won't show the google play music controls on the lock screen or pull down screen either. It's kind of annoying having to unlock my phone every time I want to skip a song or do something. Anyone else having this problem?
Hi Mackenzie. Are you using any 3rd party home launcher or lock screen app? Can you check Settings -> Apps & notifications -> Lock screen -> choose Show all notifications.
Let me know if that works.
