With PN test working, I think your settings are correct. If you still want to be sure about OS notification settings, you can try to search for similar settings in 8.1 where Focus Assist is called Quite Hours, I think and similarly others.
Also, I don’t think I’m getting many Ad notifications myself. And this would expected due to available Ad campaigns. I’m getting quite a many Brave News Ads, though. Cheers!
@zootyleon Sounds like you may have already checked things, but I wanted to pass along prior post of mine that has helped some people in the past. Would you go through and make sure to check all on your end? Steps might be slightly different as mine was showing for Windows 10, but still should apply.
I did as you’d suggested. But individual app notification customisation isn’t available for 8.1 pro I guess.
These are what was available in PC settings
