I have been trying for several months to get the notification ads to appear in Windows. Following several tutorials I came to the conclusion that I should change the region of my laptop to the United States, I did it and everything was working for a couple of weeks until it did not do it anymore, so I changed all the settings to the ones I already had.
I have an extra monitor that I use in addition to the one included with my laptop and I always have it connected to it. One day while I was playing, I disconnected the monitor to have better FPS performance and when I started to use Brave I started to get the ads.
I hope you can try this and let me know if it worked for you.
NOTE: When I reconnect the monitor I only get a couple more ads and then they stop, it always works with 1 monitor.
@CharlesKlein Sorry to bug you again on the suggestion that was just given, but I did want to verify. Did you also turn off all the automatic rules? For example, in the screenshot that @CloggyAbroad gave, Focus Assist would turn itself off when duplicating the display, playing a game, or using an app in full-screen. Sometimes people turn off Focus Assist but forget to toggle those Automatic Rules to off as well.
I just was trying to look for issues or solutions and found two different GitHub where they’ve tested and see things working with a second monitor. I also see where you mention you see them for a short and then it stops. It just feels like Focus Assist should be the issue, but double checking here.
The number of monitors you’re using should not affect whether or not ads are displayed. I currently am using a Macbook attached to two external monitors and have no issues seeing ads (this works on my windows device as well). There may be something else at play here — since you mentioned FPS, I’m curious to know if you’re using a laptop and if you have a gaming mouse connected?
So the gaming mouse is likely the cause of the issue. This is known to stop idle events in the browser which prevents ads from being shown. Can you please try disabling/disconnecting that mouse and testing to see if you get ads when not using the gaming mouse?
