I have the same issue. I toggled the following settings on and off many time. Settings -> Lock Screen -> Always On Display -> Show Music Information Settings -> Lock Screen -> Face Widgets -> Weather Settings -> Lock Screen -> Face Widgets -> Show on Always On Display During the switching, I even changed my clock style back to the default. For one moment, the song information showed up on the AOD screen, but when I changed my clock style back to my prefered one, it went away. Then I couldn't get it back, even after changing back to the defauly clock style. Currently, all of the settings are Enabled, but no music information shows up on the AOD screen.
