I managed to get ads now but I have an issue with my ultra wide monitor. When I work on my laptop without a monitor connected I can see ads directly in the Brave Browser. When I connect my ultra wide monitor I can see the ads only in the Notification Center of Windows 10. Is this known?
Furthermore the Browser does not open when I click on a notification, Windows just removes it and does nothing. When I work on my laptop the click on the ad in the Browser is working properly.
