Ah, that likely explains it. I know when installing I hit “no” on anything that sounds remotely marketing related and I turned off search and weather because they just don’t add any value and I like a clean screen. So I think the only ads I get are the small, unobtrusive ones on the lock screen, which I can’t say I’m bothered by in the slightest. I barely even notice them since it isn’t like I stare at the lock screen.
