Welcome to the forums. Long press that small icon (bubble with three dots) top left of that card, then tap the 'info' icon and see if you get the name of the app pushing the ad.How do I get rid of popup ads? When reduced they have the heading of 'android system'
Yes. That's the recent apps/multitasking overview.Thanks Javier, the bubble with three dots and Android system can only be seen when I reduce it??
